Subject: [PATCH] cr-for-branches: when doing pre-pull from incoming, take out
 lock correctly

I.e. with -f if caller specified -q, rather than always using -w.  -q
would make the script carry on if it didn't manage to get the lock and
do the pull, which would be wrong.  -w is wrong because it can block
for another long-running script.
