remember to git pull

[Brian May <brian@linuxpenguins.xyz>]

Hello,

Please remember to do a git pull before updating a package. Even more so
if you are going to do a release. Otherwise if other people have made
changes and commited them, things can get rather confusing rather
quickly. git-dpm doesn't exactly help with its .git-dpm which may have
conflicts when merging two branches.

(or even better, use the quick-update script instead)

I am just fixing the billiard package which appears to have suffered
from this problem.

Thanks.
