The underlying network transfer program, 'git-clone-pack', can
be told to clone only specified branches.  If somebody is
interested, updating the 'git-clone' wrapper to use it should
not be too hard -- obviously this needs to be done for other
transports as well, though.

cg-clone already does this.

Yes, but it can be improved.  It does fetch-pack for git native
transports, which means the receiving end expands the pack.  I
think we would either need to teach cg-clone to tell cg-fetch
that it is cloning and invoke git-clone-pack, or add an optional
"do not expand" option to git-fetch-pack (git-clone-pack always
keeps the downloaded pack unexpanded).  Huge pack transfer
spends long time on the downloader side unpacking the pack.

If you just pull tagrefs and all the objects needed for them, chances
are you'll get the whole repo anyway ;-)

Yes, that's why we changed ls-remote to report the magic ^{}
entries and it is used in cg-fetch::fetch_tags.
