Yes, that is much more user friendly.

I *guess* it may be OK at least when minfo.cur != NULL.

I believe minfo.pos points into zlemetaline. The only explicit assignment
to minfo.pos is at compresult.c:971 and :1329.

I have no idea why the else block is the appropriate place to
set origline etc, but anyway the following patch seems to solve
the *current* problem (but may break somewhere else...).


By the way, is it possible to continue the interactive mode after
accepting a match by hitting Return? I tried hitting ESC-m again
after the Return but it didn't work (either with or without the
following patch, although the behavior was different).
Hitting a key bound to accept-and-hold didn't work either. 
But I believe it is just too much hope.
