Again, this is just a preview. Dave should send the final when he thinks
it is good.

The if/else I added to the config callback is kind of ugly. I wonder if
we should have git_config_bit, or even just a function to set/clear a
bit. Then the OPT_BIT code could use it, too. Something like:

  munge_bit(flags, TRANSPORT_PUSH_FOLLOW_TAGS, git_config_bool(k, v));

Or maybe that is getting too fancy and obfuscated for a simple bit
set/clear. I dunno.
