I actually didn't care about the filename (in my script I pipe straight to tar, and in a python app I have that will use snapshots I have I planned on "opening" the url as a stream directly with the tarfile lib); it was just as easy to add both anyway.
I thought I had looked up the tar man page for an option that strips the path, clearly I missed that one. :)

I'm not sure what you mean... I never tinkered with gitweb.pl directly before.

> I wonder if you really want to allow prefix which do not end in '/'I kind of agree, yet considering its lack of "front-end" visibility it made me think of plumbing commands like git-checkout-index (which I use sometimes to replace the "missing" git export) where prefix is nothing more than an appended string to file names.
And now I remember, this is also exactly how git-archive works.

And personally, I think git-archive is the one that should add a / - it has much more visibility to end-users than this obscure query-string.
