That's a good improvement in code clarity. When I implemented
1c23 I wasn't sure what was initialized in the struct packed_git
that the HTTP code was slugging around in request->userData, and
it was hard to track down. 1c23 was a quick fix to get HTTP fetch
working again when sp/mmap merged into next.
I'm guessing you have figured out it is not actually open at this
point, which makes sense as we did fclose() calls to close out
the writer. So sha1_file.c needs to open a new file descriptor.
use_pack() will force it to be opened and the open packfile function
does update the pack_size if we don't have it yet.

fyi, we prefer "if (!pack_sig)" in Git for equality with 0 tests.
