NOTE: This fix uses is_absolute_path from msysGit-0.3.exe that is not in mingw.git yet.
Correctly test for absolute path
This fix (while correct) actually avoids another nasty bug that must be fixed later:

environment.c caches results of many getenv calls.

Under MinGW setenv(X) invalidates all previous values returned by getenv(X)

so cached values become dangling pointers.

Hi,
Our coding style does not want them extra spaces...
+ if (!is_absolute_path(gitdirenv)) {
is the way we prefer it.
Ciao,
