Sorry, I don't follow.

I didn't understand Michael's request to be
about multiple zones/regions (noncontiguous).

I think he's just saying what I was saying
earlier: to mark a "file in the region" it
should be sufficient that some part of the
file's line is in the region.  It should
not be a requirement that the full line -
all of its chars (including newline) be
within the region.

Yes, Michael did mention highlighting, but
I think what's important to him is perhaps
just that you can quickly and easily use
the region to specify a set of files to mark.

Whether the region highlight covers this or
that isn't very important, I think.  What's
surprising is that you (currently) have to
be sure to select every bit of a file's line,
for it to be marked.

Anyway, I'll stay out of this now, at least
until what Michael's asking for gets
clarified.
