I think some documentation updates are needed here?

In my month-old build from master, at any rate:

(info "(elisp) %-Constructs") states that ‘%m’ and ‘mode-name’
are equivalent, which is evidentially wrong.

Tangentially, (info "(elisp) Mode Line Variables") makes mention
of %M as being an obsolete version of ‘global-mode-string’, and
the %M construct is not listed in that other node at all (and
conversely, 'mode-name' is mentioned in the latter node without
any reference to %m.)
