It may be more complete but it is obviously untested.  Please help me
trust you better with your future patches.  Because I personally do not
run gitweb myself, I really need a trustworthy lieutenant(s) in the area.

Trading a gitweb with a small bug with a gitweb that does not even pass
its test script does not feel like a good change to me.

I think the breakage is the "close $fd" at the end of this hunk:

I'll queue it to 'pu', with the "close $fd" removed, for now.
