v0.5.20

Added

• Yanks reach your local clipboard over SSH. binvim now emits the terminal
  OSC 52 escape alongside its usual arboard clipboard write, so a yy inside
  a binvim running on a remote box lands on the clipboard of the machine you
  are sitting at. It covers every unnamed-register write — yy, dd, cc,
  the terminal and AI pane copies — matching what the local clipboard mirror
  already did. Configured by [clipboard] osc52, which defaults to "auto":
  the sequence goes out over SSH and is skipped locally, where arboard has
  already done the work and the escape would only put every yank, base64'd,
  into any script / asciinema / tmux log of the session. true and false
  force it. Inside tmux or screen the sequence is also sent through the
  multiplexer's DCS passthrough, so either set-clipboard on or
  allow-passthrough on is enough to make it work.
  Thanks to @happyTonakai.

Fixed

• CJK and other wide characters no longer put the cursor in the wrong
  column. Every column walk in the editor advanced one cell per character,
  but the terminal draws a CJK glyph in two — so the cursor sat mid-glyph,
  clicks landed on the wrong character, and the end of a CJK-heavy line was
  unreachable because the viewport thought the line was half as wide as it is.
  Cursor placement, click-to-position, horizontal scrolling, the markdown
  conceal walks and hover-popup sizing now all measure real terminal width.
  A wide glyph that straddles the edge of a split is drawn as < or >
  rather than spilling a cell into the pane next door, and combining marks
  compose onto the character they belong to instead of consuming a column.
  Thanks to @happyTonakai.

Changed

• A public fork is allowed when it exists to prepare a contribution. GitHub
  cannot open a pull request from a private fork to a public repository, so the
  old "private forks only" rule ruled out the one contribution path the licence
  invites. BSAL v1.1 defines a Contribution Fork instead: public is fine, as
  long as it keeps the fork relationship, publishes no releases, isn't run as a
  project of its own, and is deleted or made private once the PR closes.
