MinGW port updated to GIT 1.5.0

I've merged GIT 1.5.0 into the MinGW port. It is available at the usual location:

pull/clone: git://repo.or.cz/git/mingw.git gitweb: http://repo.or.cz/w/git/mingw.git

It contains an important fix (MinGW specific): Earlier versions could sometimes create temporary files read-only instead of read-writable.

WARNING!

The MinGW port does not support symbolic links, but the git.git itself now contains a symbolic link (RelNotes). For this reason, you cannot successfully pull this version's "master" branch to your Windows box and expect it to work. The "devel" branch has the symbolic link removed, so it can at least be checked out. For other operations you may enounter an error like this:

bad tree object: 4571d0d1cfb5a4170dfc80e9654228acae295129

I'm working on a solution. The general idea is to extend the meaning of `core.filemode = false` to check out symbolic links as plain files. Any hints about where the source code needs changes are welcome.
