This LGTM, but is it actually what we want?  Referencing everything
from everything seems to defeat the purpose.  I would expect
notmuch(1) to reference everything, but the command manpages to only
reference notmuch(1) and specific, related commands (e.g., dump and
restore should reference each other; new should reference hooks;
count, dump, reply, search, show, and tag should reference
search-terms; and new, search, and reply should reference config).
