The result of abs_path() three lines below the cited context is never
passed to git; only its trailing part is ever used. This does not seem to
be problematic on Windows, according to the test suite.
The other use if abs_path() is about bare repositories and that is
certainly problematic, but nobody uses the tools written in perl in a bare
repository on Windows, obviously, otherwise we would have heard complaints. ;)

Since you keep repeating "does not work", without any specifics, I can't
help (and I'm not going to find out myself what "does not work").
