Richard, 

Unfortunately, even after reading the updated docstring several times
and experimenting, I still can't visualize what
blink-matching-paren-dont-ignore-comments is supposed to do. I also
looked for an example in (Info-find-node "emacs" "Matching") but there
is no mention of this variable there, either.


M-x describe-variable blink-matching-paren-dont-ignore-comments:

blink-matching-paren-dont-ignore-comments is a variable defined in `simple.el'.
Its value is t

Documentation:
*nil means `blink-matching-paren' ignores comments.
More precisely, when looking for the matching parenthesis,
it skips the contents of comments that end before point.

Puzzled,
Andy Scott
