bug#69220: [PATCH] smerge-mode: add a function to resolve all conflicts in a file

No, that's not what I'm suggesting.  If you re-read the above I say
"applied to every conflict in the buffer" (rather than some specific N),
and I don't say "resolve" or anything like "resolution".

It's really doing the same as your patch, except that the command to
apply at each iteration is not limited to one of
`smerge-keep-(upper/base/lower)` (and that it's specified by hitting the
command's key binding rather than by choosing a string in the minibuffer).

BTW, your use of [upper base lower] as a completion table is both cute
and horrible at the same time :-)
