Maybe it would be nice to have a "update this sub" aka git-pull as a built-in feature?
We have this in 37 as 37-update, but its usage is pretty uncommon:
# Usage: 37 update
# Summary: Pulls the latest changes from GitHub.
GIT_DIR="$_37_ROOT/.git" git "$@"
echo "Updating 37!"
37git reset --hard origin/master
I didn't know if it was important or not to bring this kind of script into the main sub repo. If there's clamoring for it we could consider it.
