Change it how?  I don't see how max-verbose and extra-verbose can be
combined, since the former is an int and the latter a bool.

As you said later, it'd have to show as «'' -- exactly» or « --
exactly».  (Or we could teach the C code to take '*(om=5)' for "exactly
five")

I mentioned the lack of "exactly" as a difference, but now that I think
about it, I suppose I think the "exactly" _should_ be displayed: firstly,
because displaying more options is better; secondly, because it is
displayed in non-verbose mode, and it'd be odd for setting the "verbose"
style to cause fewer options to be offered.

Another display option would be to use a dummy "string without a match"
as Bart said (compadd -E1) for something like

    → sense
    (for the "exactly" sense, skip/omit this field)
    + -- before
    - -- since

Got it, thanks.
