Evidently I fooled myself with my test case on this one.  I thought
that errflag nonzero would prevent any further commands from executing
in the calling function X, but the use of a new flag value avoids
that, so X proceeds.

However, the accept-* family are not the only other widgets that can
have confusing side-effects if run after push-line-or-edit, most
obviously get-line.
