The number of loose objects at which git-gui shows a gc warning has
historically been hardcoded to ~2000, or ~200 on Windows. The warning can
only be disabled completely via gui.gcwarning=false.
Especially on Windows, the hardcoded threshold is so ridiculously low that
git-gui often complains even immediately after gc (due to loose objects
only referenced by the reflog).
'git gc --auto' uses a much bigger threshold to check if gc is necessary.
Additionally, the value can be configured via gc.auto (default 6700).
There's no special case for Windows.
Change git-gui so that it only warns if 'git gc --auto' would also do an
automatic gc, i.e.:
- calculate the threshold from the gc.auto setting (default 6700,
disabled if <= 0)
- check directory .git/objects/17
We still check four directories (14-17) if gc.auto is very small, to get a
better estimate.
