Ok, I think I got it. How about this on top of Felipe's patch?

The point is that __git_func_wrap() is not a template function
processed by _GIT_complete() (or whatever we'll end up calling it)
anymore, but simply a wrapper function around existing completion
functions. The name of the completion function to be invoked should
be given as argument. _GIT_complete() then uses 'eval' to create
another wrapper function to invoke __git_func_wrap() with the name of
the desired completion function. The name of this dynamically created
wrapper function is derived from the name of the command or alias,
i.e. for 'gf' it will be __git_wrap_gf().
The overhead of the additional function call is not even measureable,
while it would spare the overhead of fork()ing a subshell and
fork()+exec()ing 'sed' twice when loading the completion script and
then for each subsequent alias.
Best,
Gábor
