merge: separate out "both created" cases

When 'f' is not in 'ma', 'a' will be 'nullid' and all the if/elif
conditions that check whether some one nodeid is equal to 'a' will
fail, and the else-clause will instead apply. We can make that more
explicit by creating a separate 'm' action for the case where 'a' is
'nullid'. While it does mean copying some code, perhaps it makes it a
little clearer which codepaths are possible, and which cases the
"Note:" in the code refers to. It also lets us make the debug action
messages a little more specific.

#require serve fifo

Test hangup signal in the middle of transaction

  $ hg init
  $ mkfifo p
  $ hg serve --stdio < p 1>out 2>&1 &
  $ P=$!

Do test while holding fifo open

  $ (
  > echo lock
  > echo addchangegroup
  > start=`date +%s`
  > # 10 second seems much enough to let the server catch up
  > deadline=`expr $start + 10`
  > while [ ! -s .hg/store/journal ]; do
  >     sleep 0;
  >     if [ `date +%s` -gt $deadline ]; then
  >         echo "transaction did not start after 10 seconds" >&2;
  >         exit 1;
  >     fi
  > done
  > kill -HUP $P
