Git repos can be created outside the $GITHOME directory about gitreceive HOT 1 OPEN

For me, the git user cannot write outside their home directory so this fails with permission denied. I know it's best practise not to just hope for sane permissions particularly when dealing with security, but is there a sane use case where someone wants relative paths when pushing, for instance pushing configuration files into etc?

Instead of removing / from the repo name, perhaps it's better to just disallow relative paths by removing ..

Also that perl call has been replaced by sed.
