[MinGW PATCH] 'git clone git://...' was failing inside git-read-tree with 'fatal: Not a valid object name HEAD'

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.
