This test fails occasionally[1] because the order of events and the
number of events varies across runs.
We should always call draw_status exactly 3 times:
[*git*][fifo]
[*git*]
Commit subject etc. [*git*]
Let's check it this way.
This seems to work; this time I took the time to run it a couple
hundred times and in Cirrus CI.

Commit 53d9b9b67 (Escaping tweak in git.kak, 2024-02-06) broke
blame-jump when the commit subject contains a single quote.
(Also on unbalanced "{" which is a rare edge case but we already have
it in our Git history.)
git.kak assumes that filenames don't contain ' or unbalanced {,
but we can't really make that assumption about people's names or
commit subjects.
Unfortunately the escaping here is very messy. We need to pass
arbitrary text to callbacks; maybe we should have closures that can
capture private temporary registers.
