Thanks guys for the quick reply and suggestions!
Ken: yeah, I can see how messy that's going to be; alas that
%(trim) indeed doesn't return its result. Although I'll probably
see this again, it'd be maybe 1x/year for the next couple years.
(And, who knows, maybe their IT department will fix it? B-) Not
worth complicating my replcomps; easier to just manually add the
"To:" field in vim. B-)
Thanks!
Bob

Hi Bob,
Is there a concise way to specify "if X is not present or is just
white space?" in one's replcomps?
I'd look into applying function `trim' first; see mh-format(5).
If this command is of any use, I started to use it to explore that but
ran out of time:
fmttest -format '%<{reply-to}%|%<{from}%>%>%(void(width))%(putaddr To: )\n'
A msg or -file switch can be added.

We covered this ground a few years ago, here:
http://lists.nongnu.org/archive/html/nmh-workers/2015-02/msg00139.html
Priescently, I said back then:
Mind you, a header consisting of nothing but white space will be read
as "true" in the sense of mh-format(5) tests
And just to be sure:
% fmttest -raw -format '%<(nonnull{text})Non-null%|Null%>' ''
Null
% fmttest -raw -format '%<(nonnull{text})Non-null%|Null%>' ' '
Non-null
But I see:
% fmttest -raw -format '%(trim{text})%<(nonnull)Non-null%|Null%>' ' '
Null
So Ralph was right, %(trim) does what you want. But ... %(trim) does
not have a return value (that was probably a mistake), so you cannot use
it directly as a condition for %<. You'll have to make sure your first
test is against the str register rather than Reply-To, and making it work
for all components is actually going to be a bit messy.
You know, since this the first one you've encountered in 30 years, maybe
it is better just to let it go?
