I wanted a solution which works. I didn't consider this until it was
merged in (see my last reply). I don't think special-file-types are
a solution, I want this to work out of the box so that a service I want
to write for gitolite will work.
It can be a solution if it would work with the service and when it will
be documented as a requirement for gitolite. The off-the-shelves status
of gitolite is broken, you are not informed about these shebangs..
