As a suggestion, git allows for aliases to be defined in your .gitconfig file

[alias]
    desc = describe --always --dirty

then use:
git desc


Also, for cloning and checking out a specific branch you can use:
git clone git://github.com/MythTV/mythtv.git -b fixes/0.24
to check out the 0.24-fixes branch in one go.

Then,
git pull
to get updates.

Really, just read the git man pages. They're insanely helpful and I've
never seen a set of man pages that are so complete.
