Comment (by nickm):

 I've updated the branch and PR at
 ​https://github.com/torproject/tor/pull/1339 .

 There are now tests, in the form that python's doctest module.  I've
 opened a new ticket #31869 to run them automatically.  To try them
 yourself, run "python -m doctest
 ./scripts/maint/annotate_ifdef_directives.py"

 I've tried to document the 79/80 character issue and the newline handling
 more carefully.

 I've added some code to produce balanced parentheses.

 Predictably, adding tests found a bug in the negation-processing code: I
 had exchanged two characters in a regular expression.  I added a fixup!
 commit to handle that.

 I'll put this back in needs_review once CI has passed.
