update: improved help text
Using the term "the repository's working directory" instead of just "working
directory" to make it nearly impossible to confuse it with $PWD.
Also, this new wording better conveys the fact that update applies
to the working dir as a whole (no matter what the $PWD currently is).
#!/bin/sh
op=`basename $0 | sed -e 's/^git-//'`
exec hgit $op "$@"
