I'll let that for others to do then -- I just wrote a throwaway thing to scan
the Emacs sources and got about 150 complaints, some of which very much look
like bugs.
Complaining about \] didn't seem very productive so that particular warning
went away, since it is common to match square brackets in pairs and [ needs to
be escaped. There is also a new repetition-of-repetition check.
