Subject: git-cvsexportcommit: Fix calling Perl's rel2abs() on MSYS
X-Git-Tag: v1.7.9-rc1~3^2

git-cvsexportcommit: Fix calling Perl's rel2abs() on MSYS

Due to MSYS path mangling GIT_DIR contains a Windows-style path when
checked inside a Perl script even if GIT_DIR was previously set to an
MSYS-style path in a shell script. So explicitly convert to an MSYS-style
path before calling Perl's rel2abs() to make it work.

This fix was inspired by a very similar patch in WebKit:
