You can also pass --look-for-adds (-l) to darcs record; if you want this
to be the default behaviour, you could add "record look-for-adds" to
~/.darcs/defaults or similar.

This sounds like bad advice; merging changes with locally unrecorded
changes shouldn't be any less expensive than merging them with a
just-recorded patch (the algorithm is exactly the same, after all,
unless there's something I've missed), and you have no way to roll
things back if you don't record a patch before merging.
Of course, you may want to unrecord your temporary patch after you've
pulled, to keep your patch history neater.
