I use SMerge quite a lot, but never yet had a situation where the same
resolution was applicable to all of the conflicts, let alone knew that
in advance, before looking at each conflict.

I'm also guessing one could have the same effect by giving a prefix
argument of suitable value to the conflict-resolution command.

Having said that, if this is deemed useful, why not?  Adding Stefan to
the discussion, in case he has comments.  I'd also be interested in
Dmitry's opinions.

Thanks.
