Hmmm. Considering my lua isn't very good yet, how about the following
shell script (that is called from lua but only if the branch has been
received) for now:
address@hidden:~/tree/config$ cat ~/bin/update
#!/bin/sh -e
cd "$1"
heads=`mtn automate heads "$2" | wc --lines`
if [ "$heads" -gt 1 ]
then
echo "Too many heads" >&2
exit 0;
fi
diff=`mtn diff | wc --lines`
if [ "$diff" -gt 3 ]
then
echo "Local changes made" >&2
exit 0;
fi
mtn update --branch="$2"
address@hidden:~/tree/config$ ~/bin/update $PWD
au.com.microcomaustralia.brian.config
mtn: updating along branch 'au.com.microcomaustralia.brian.config'
mtn: already up to date at 8bd00cf9a82b9f0bd52988666cb65e5f950e6854
Hmm. It works, although I am not entirely happy with the check to see
if anything has changed or not in the workspace.

Yes, this might be a problem. I saw a lua test case in monotone or
something that used chdir, and thought it might work, but may have
been confused. In any case, such an operation is likely to mess
monotone up.

Yes. Agreed.
