v7.5.6 — the leak guard catches writes whose status line does not change

Fixed

• The leak guard catches writes whose status line does not change. It compared git status
  lines before and after the run, so it missed a further edit to a file that was already modified,
  a new file inside a directory that was already untracked, and an edit to an untracked file. The
  snapshot now also hashes the content of every modified or untracked file. A commit in your
  checkout (>>> HEAD moved: <old> -> <new>) and a deleted untracked file now count as a leak too.
  Paths that were dirty before the run are named (>>> already dirty before the run…), because the
  saved patch holds your earlier edits there as well. Non-ASCII file names are listed as-is instead
  of git-quoted. Gitignored paths stay out of scope.
