rej -M skips the merge program, so rej -a -M will give you something like
this:
coffee:/local/linux.p # rej -a -M drivers/ide/ide.c.rej
drivers/ide/ide.c: 1 matched, 0 conflicts remain
But I would want to go over the bit that calculates the conflicts remaining
more carefully if people plan on trusting this ;) It'll run on unified diffs
too, although it will be slower then patch since the assumption is the quick
and easy placement patch does has already failed. (that's easy enough to fix
though).

you can rej -m kdiff3|meld|tkdiff or any program that does a side by side
comparison of two files. (export REJMERGE=foo sets the diff prog as well)
I use rej frequently to merge patches in here, but that is mostly because
there is no easy way to get the common ancestor and parent revision of the
patches I'm merging.
With that info in hand, kdiff3 is pretty nice. You would have to spoon feed
it the renames, but it should have most of the other features you're looking
for, including the 'no gui if all conflicts are auto-solvable'
