2.23.3: Highlight removed trailing newline after added lines

If you add a couple of new lines at the end of some file, the last of
which does not end with a newline, with this release the new section
will have a marker at the end indicating it's losing a newline.

2.23.2: Fix a race condition

With "No newline at end of file" handling.

2.23.1: Handle "No newline at end of file" in multiple languages

Ref: https://github.com/walles/riff/issues/39

2.23.0: Improve "No newline at end of file" rendering

If an EOF linefeed is added or removed, indicate using ⏎ characters in
the diff on what line it was added / removed.

2.22.2: Add a Windows build

Also fix some Windows specific issues, and a highlighting bug.

2.22.1: Don't crash on large hunks

Before this release, if a hunk was too large riff would take forever and
use up unreasonable amounts of memory, sometimes to the point of
crashing.

With this release, if a hunk is too large riff won't refine it but just
pass it through as-is, working around the related performance issues.

2.22.0: Improve "git log -p" highlighting

When showing logs with embedded diffs, highlight the start of each
commit with a blue background extending to the end of the line. This
makes it much easier to see where each commit starts and ends when
scrolling up and down.

2.21.0: Improve support for "git log" highlighting

By highlighting "commit" lines just like git. With this version I
recommend setting git's pager.log to riff as well.

2.20.0: Better highlighting of added / removed files

Or actually lowlighting. The +++ and --- /dev/null lines are now
lowlighted in this release, as are the file modes of deleted files.

2.19.0

Highlight copy and rename operations
