The real reason it uses a bit per given ref is what it wants to
show is different from what gitk shows.  It wants to show which
ones are reachable from which head on each commit -- in gitk the
user has to follow the line to find it out.

However, to track 300 branches, you would need a terminal with
360 columns or so, _and_ you have to count columns to see if a
given commit is reachable from the ref you are interested in, so
it is not useful at all in practice to do more than a handful
refs at a time.
