I didn't like that too much either.

Yeah, I'm also thinking that re-generating the script is not bad enough
to introduce this complexity.

I think it would be nice to allow the user to manually
source git-completion.tcsh, in case they want to make
manual modifications to it.
I think the most user-friendly option is to actually re-generate the
script each time. It feels wrong, but it works well :)
