Just a couple of minor comments.

This is only set to false once per process invocation. We do not
currently talk with more than one remote from the same process in
the "fetch" codepath, and we must maintain that. This fix will be
broken otherwise ("recursive submodule fetch" comes to mind; one
more reason it should do its submodule business in a separate
process).

This codepath still forgets to check if the other side advertised
"thin-pack", "no-progress", and "include-tag", no?

This is initialied to 0 per communication, so having multiple
remote.$there.pushURL configuration variables will work correctly.
