Using the hg repo from a few days ago, selecting parenthesis highlighting
from the menu bar doesn't actually do anything. It seems to me that this
used to work.
Recipe: xemacs -vanilla. Use the menu Options->Display->Paren Highlighting
and select any of the options. Edit your favorite C or Lisp file and place
the cursor on some closing brace/paren. No highlighting is done.
But use customize-group to enable paren highlighting, and paren highlighting
is actually enabled. I'm not exactly sure what the problem is, but if you
used the menu to enable paren highlighting and then save it to the custom.el
file, you get something like
(paren-mode 'sexp t)
But if you use customize, you get
(paren-mode 'sexp nil (paren))
which seems to work when restarting xemacs.
Also, the documentation for paren-mode mentions sexp-expression (and the
unimplemented nested), but the menu option doesn't list sexp-expression. It
should probably mention that.
