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.
