-"                           fonts in the generated CSS.
-"   7.4_v1  (Vim 7.4.0000): Fix modeline mangling for new "Vim:" format, and

-"}}}
-"
-"   7.3 updates: {{{
-"   7.3_v14 (Vim 7.3.1246): Allow suppressing line number anchors using
-"			    g:html_line_ids=0. Allow customizing
-"			    important IDs (like line IDs and fold IDs) using
-"			    g:html_id_expr evaluated when the buffer conversion
-"			    is started.
-"   7.3_v13 (Vim 7.3.1088): Keep foldmethod at manual in the generated file and
-"			    insert modeline to set it to manual.
-"			    Fix bug: diff mode with 2 unsaved buffers creates a
-"			    duplicate of one buffer instead of including both.
-"			    Add anchors to each line so you can put '#L123'
-"			    or '#123' at the end of the URL to jump to line 123
-"			    (idea by Andy Spencer). Add javascript to open folds
-"			    to show the anchor being jumped to if it is hidden.
-"			    Fix XML validation error: &nsbp; not part of XML.
-"			    Allow TOhtml to chain together with other commands
-"			    using |.
-"   7.3_v12 (Vim 7.3.0616): Fix modeline mangling to also work for when multiple
-"			    highlight groups make up the start-of-modeline text.
-"			    Improve render time of page with uncopyable regions
-"			    by not using one-input-per-char. Change name of
-"			    uncopyable option from html_unselectable to
-"			    html_prevent_copy. Added html_no_invalid option and
-"			    default to inserting invalid markup for uncopyable
-"			    regions to prevent MS Word from pasting undeletable
-"			     elements. Fix 'cpo' handling (Thilo Six).
-"		 7.3_v12b1: Add html_unselectable option. Rework logic to
-"			    eliminate post-processing substitute commands in
-"			    favor of doing the work up front. Remove unnecessary
-"			    special treatment of 'LineNr' highlight group. Minor
-"			    speed improvements. Fix modeline mangling in
-"			    generated output so it works for text in the first
-"			    column. Fix missing line number and fold column in
-"			    diff filler lines. Fix that some fonts have a 1px
-"			    gap (using a dirty hack, improvements welcome). Add
-"			    "colorscheme" meta tag. Does NOT include support for
-"			    the new default foldtext added in v11, as the patch
-"			    adding it has not yet been included in Vim.
-"   7.3_v11 ( unreleased ): Support new default foldtext from patch by Christian
-"			    Brabandt in
-"			    http://groups.google.com/d/topic/vim_dev/B6FSGfq9VoI/discussion.
-"			    This patch has not yet been included in Vim, thus
-"			    these changes are removed in the next version.
-"   7.3_v10 (Vim 7.3.0227): Fix error E684 when converting a range wholly inside
-"			    multiple nested folds with dynamic folding on.
-"			    Also fix problem with foldtext in this situation.
-"   7.3_v9  (Vim 7.3.0170): Add html_pre_wrap option active with html_use_css
-"			    and without html_no_pre, default value same as
-"			    'wrap' option, (Andy Spencer). Don't use
-"			    'fileencoding' for converted document encoding if
-"			    'buftype' indicates a special buffer which isn't
-"			    written.
-"   7.3_v8  (Vim 7.3.0100): Add html_expand_tabs option to allow leaving tab
-"			    characters in generated output (Andy Spencer).
-"			    Escape text that looks like a modeline so Vim
-"			    doesn't use anything in the converted HTML as a
-"			    modeline. Bugfixes: Fix folding when a fold starts
-"			    before the conversion range. Remove fold column when
-"			    there are no folds.
-"   7.3_v7  (Vim 7-3-0063): see betas released on vim_dev below:
-"		  7.3_v7b3: Fixed bug, convert Unicode to UTF-8 all the way.
-"		  7.3_v7b2: Remove automatic detection of encodings that are not
-"			    supported by all major browsers according to
-"			    http://wiki.whatwg.org/wiki/Web_Encodings and
-"			    convert to UTF-8 for all Unicode encodings. Make
-"			    HTML encoding to Vim encoding detection be
-"			    case-insensitive for built-in pairs.
-"		  7.3_v7b1: Remove use of setwinvar() function which cannot be
-"			    called in restricted mode (Andy Spencer). Use
-"			    'fencoding' instead of 'encoding' to determine by
-"			    charset, and make sure the 'fenc' of the generated
-"			    file matches its indicated charset. Add charsets for
-"			    all of Vim's natively supported encodings.
-"   7.3_v6  (Vim 7.3.0000): Really fix bug with 'nowrapscan', 'magic' and other
-"			    user settings interfering with diff mode generation,
-"			    trailing whitespace (e.g. line number column) when
-"			    using html_no_pre, and bugs when using
-"			    html_hover_unfold.
-"   7.3_v5  ( unreleased ): Fix bug with 'nowrapscan' and also with out-of-sync
-"			    folds in diff mode when first line was folded.
-"   7.3_v4  (Vim 7.3.0000): Bugfixes, especially for xhtml markup, and diff mode
-"   7.3_v3  (Vim 7.3.0000): Refactor option handling and make html_use_css
-"			    default to true when not set to anything. Use strict
-"			    doctypes where possible. Rename use_xhtml option to
-"			    html_use_xhtml for consistency. Use .xhtml extension
-"			    when using this option. Add meta tag for settings.
-"   7.3_v2  (Vim 7.3.0000): Fix syntax highlighting in diff mode to use both the
-"			    diff colors and the normal syntax colors
-"   7.3_v1  (Vim 7.3.0000): Add conceal support and meta tags in output

-"     by Erik Falor

-"   * Add optional argument to :TOhtml command to specify mode (gui, cterm,

-"   * Add way to override or specify which RGB colors map to the color numbers
-"     in cterm. Get better defaults than just guessing? Suggestion by "nacitar".
-"   * Disable filetype detection until after all processing is done.
-"   * Add option for not generating the hyperlink on stuff that looks like a

-"     when hovering)?
-"   * Bug: Opera does not allow printing more than one page if uncopyable
-"     regions is turned on. Possible solution: Add normal text line numbers with
-"     display:none, set to display:inline for print style sheets, and hide
-"      elements for print, to allow Opera printing multiple pages (and
-"     other uncopyable areas?). May need to make the new text invisible to IE
-"     with conditional comments to prevent copying it, IE for some reason likes
-"     to copy hidden text. Other browsers too?
-"   * Bug: still a 1px gap throughout the fold column when html_prevent_copy is
-"     "fn" in some browsers. Specifically, in Chromium on Ubuntu (but not Chrome
-"     on Windows). Perhaps it is font related?
-"   * Bug: still some gaps in the fold column when html_prevent_copy contains
-"     'd' and showing the whole diff (observed in multiple browsers). Only gaps
-"     on diff lines though.
-"   * Undercurl support via CSS3, with fallback to dotted or something:
-"	https://groups.google.com/d/topic/vim_use/BzXA6He1pHg/discussion
-"   * Redo updates for modified default foldtext (v11) when/if the patch is
-"     accepted to modify it.
-"   * Test case +diff_one_file-dynamic_folds+expand_tabs-hover_unfold
-"		+ignore_conceal-ignore_folding+no_foldcolumn+no_pre+no_progress
-"		+number_lines-pre_wrap-use_css+use_xhtml+whole_filler.xhtml
-"     does not show the whole diff filler as it is supposed to?
-"   * Bug: when 'isprint' is wrong for the current encoding, will generate
-"     invalid content. Can/should anything be done about this? Maybe a separate
-"     plugin to correct 'isprint' based on encoding?
-"   * Check to see if the windows-125\d encodings actually work in Unix without
-"     the 8bit- prefix. Add prefix to autoload dictionaries for Unix if not.
-"   * Font auto-detection similar to
-"     http://www.vim.org/scripts/script.php?script_id=2384 but for a variety of
-"     platforms.
-"   * Pull in code from http://www.vim.org/scripts/script.php?script_id=3113 :
-"	- listchars support
-"	- full-line background highlight
-"	- other?
-"   * Make it so deleted lines in a diff don't create side-scrolling (get it
-"     free with full-line background highlight above).
-"   * Restore open/closed folds and cursor position after processing each file
-"     with option not to restore for speed increase.
-"   * Add extra meta info (generation time, etc.)?
