Release v1.1.0

[v1.1.0] – 2026-07-19

Added

• Bundled filetype plugin (ftplugin/xxd.vim) with dump-editing
  defaults — tabstop=10, expandtab, shiftwidth=3 (one hex byte),
  no automatic formatting, wrapping or indenting — applied to any
  buffer with filetype=xxd and fully reverted via b:undo_ftplugin
  when the hex view is toggled off (including buffers whose original
  filetype was empty, where no FileType event fires). Suppress with
  let b:did_ftplugin = 1 in a personal ftplugin/xxd.vim, or
  override individual settings in after/ftplugin/xxd.vim
  (:help hexpair-ftplugin).

• g:hexpair_paste (default on): the global 'paste' option is
  switched on while the cursor is in a hex-mode buffer and restored to
  its previous value when the cursor leaves it or hex mode is toggled
  off, so insert-mode mappings and abbreviations cannot mangle typed
  hex; all other buffers keep the user's own 'paste' state. The
  buffer's 'expandtab' is preserved across the switch.

• Dump validation: a character in the hex area that is not a hex
  digit, or an odd total number of hex digits, now aborts :w and
  hex-mode toggle-off with an error and the cursor parked on the
  offender, instead of silently dropping data — the file on disk and
  the dump keep their previous content. This also limits the damage
  after an u that undid the conversion itself: the non-dump content
  is refused rather than converted.

• :e / :e! while hex mode is active now regenerates the dump from
  the freshly read file and keeps hex mode and the cursor byte offset,
  instead of leaving raw binary content in a buffer that still
  believed it was a dump.

Changed

• Documented mapping examples now use the conventional <Leader>
  prefix instead of §, which only exists on some keyboard layouts
  (e.g. Czech); the plugin still defines no mappings of its own. The
  help and README now also explain the <Leader>/mapleader and
  <Plug> mechanisms for readers new to them.
