(git.portable) git/cmd should be in PATH instead of git/bin

[kwencel]

I think the git\cmd directory should be in PATH instead of git\bin.

It can create problems if there is another bash.exe on the PATH (WSL or win-bash project for instance). CMake also has problems building C++ projects if it detects sh.exe on the PATH. The README of the PortableGit archive that is extracted by this package also suggests using the cmd directory in the PATH.

This is the only for this reason I have to use the git.install package which makes this configurable and I'd really like to use a portable install instead. I would really appreciate if this could be changed or at least configurable.
