New version of sgit - many improvements
Now allows to not overwrite files. Now allows sed options to be passed to sed. Allows specifying path to sed. This script now has its own repo at https://github.com/xexyl/sgit. I don't expect many people to use it but it seemed like it was worthy of a repo as it is a pretty handy script (though far from perfect).
