Two more notes:

1. In case it wasn't clear, the problem with the alias is that `git
   prop' would work with a path that is relative to the plt repository
   root -- once you switch to the script, it would work with the files
   relative to where you invoke this command from.

2. This is a slightly better version which will properly error out if
   you're not in a git repository.

     top="$(git rev-parse --show-toplevel)" || exit 1
     exec "$top/collects/meta/props" "$@"
