Thanks, Alan.

If the repository is kept clean (no un-comitted) changes, you can
just do "git checkout <branch_name>" (where branch_name would be
"master", or the binutils active branch, or GDB's active branch).
With git, branch changes are really fast.

On the other hand, we might want to keep all commits as close as
possible to the midnight mark, so that we don't have to delay too
much the GDB scripts. If we use multiple copies of the repo, we
avoid the time it takes to switch between branch, which takes,
on my laptop, between 1 and 3 seconds.

But on the other hand of the other hand, we already have the delay
it takes to fetch new changes, and unless your script was programmed
to fetch only the branch you want, you'd be fetching the same data
3 times, which can add to the delay.

The bottom line is that I'm thinking way too much into this, and that
you probably don't really have any real reason to change a thing :).

Is the script running on sourceware? If you'd like, we can share
responsibility of the script, and help out with the git part.
