        Why would you want to do that when you can clone the whole thing and
        then just check out what you want?

    Why clone master when you really want master-1.12?

    Before I RTFM'd and discovered the --branch command I used to do as
    you suggest but it seemed quite a waste:

    git clone [...] master-1.12

    git checkout origin/master-1.12 -b master-1.12
    git branch -D master

    Note that I really want a separate directory that is dedicated to
    master-1.12.  The whole do-everything-in-one-directory thing takes
    entirely too long (right now I can test a fuzz failure against 3 or
    more branches in parallel without even having to wait for a
    recompile let alone deal with all the mess that gets left behind
    when switching major branches--look at git status after switching
    from a master-1.10 compile to master for an example).

On Unixen (all non-windows platforms) git ships with an additional
script hidden away called 'git-new-workdir' which allows you to do just
that by using symlinks, so you can have multiple working directories on
multiple branches, all working off of a single actual clone.

Caveats are:
- I have no idea how to do that on Windows
- If you accidentally break the implicit rules (i.e. you checkout master
in your master-1.12 directory) all hell breaks loose.
Yeah, I saw that mentioned here before but never bothered.  Disk space 
is cheap. :-)  (And I've already had to wipe out and rebuild my git 
directories enough times that I'm wary of trying any new commands...)
