commitctx: gather more preparation code within the lock context
This is a small change that exist mostly for clarification. I am about to move a
large amount of code in its own function. having all that code next to each
other will make the next changeset clearer.
#require serve
$ hg clone http://localhost:$HGPORT/ copy

$ test -d copy

$ "$PYTHON" "$TESTDIR/dumbhttp.py" -p $HGPORT --pid dumb.pid
$ cat dumb.pid >> $DAEMON_PIDS
$ hg clone http://localhost:$HGPORT/foo copy2
