There're several blink-matching-paren-* options in file <simple.el>,
but no option's name is blink-paren-*.  So I think perhaps it's better
to rename it to blink-matching-paren-highlight-offscreen.

Following your instruction, I defface blink-matching-paren-offscreen.

Got it.  It seems that <www.gnu.org/software/emacs/CONTRIBUTE> need to
be changed; it said "Limit lines in commit messages to 78 characters".

New patch is attached.  I have checked that there's no conflict
between the 2 newly introduced names and the original names.
