This was ten years ago, and "pending" is still somewhat confusing, but
I've now added the text to the manual in Emacs 29.

I agree that "pending" isn't very informative here, but I don't really
have a suggestion for a clearer wording.  In the "is*" case, we want to
say "we've recalculated (and possibly added more) matches", which is
unusual when isearching, so it's probably nice that we get a message for
that.  But something like "Recalculated" instead of "Pending" might be
nice?

In the \| case, we're probably waiting for more data, so "Pending" is
fine there, but I don't think we really can separate between the two
cases, can we?  "foo\|" is a valid regexp; it's just very odd.

So I dunno.  Perhaps just leaving it as is is the best solution.  Any
opinions?
