Christoph Reiter 11a162b0e5 repo: make file executable permissions match the cygwin derived status
In case we have a git clone from Linux that is accessed via cygwin git
the files executable status will be derived from the file content (shebang)
and won't match the git repo, leading to a initially dirty tree.

This can be worked around by setting "core.filemode=false", but let's try
to match the cygwin permissions with the in-repo permissions so this isn't
needed.
