Hmm.

Notmuch emacs client runs `notmuch search --output=tags '*'` 
and then `notmuch count --batch` for those. If that 'certain'
tag was in output of notmuch search --output=tags '*' then I
don't see a reason it not showing up (unless it somehow were
included in notmuch-hello-hide-tags, but I cannot see how it
could be there). 

I personally don't have any tags excluded and nothing related
to *hello* in my ~/.emacs.d/custom.el -- and now that I 
experimented with [search] exclude_tags I just could not get
it to work in any related way (the tag I try to exclude is
seen in search --output=tags '*' and in notmuch count --batch
outputs...

    $ notmuch config get search.exclude_tags
    tbd
    $
    $ notmuch count --batch
    tag:tbd
    1
    $
    $ notmuch search --output=tags '*' | grep tbd
    tbd

Finally, I tried adding another tag to the one message
with this 'tbd' -- and that another tag is shown in
"All tags:" output.

That doesn't mean there could not be a bug there, just
that I cannot reproduce it...
