The only gain with the current way is that Emacs will point out 
the mismatch (considering my Makefile example), if the cursor is 
on the opening '('.  With my suggested method, it's not the 
mismatch which would be shown, but the pair of '(' would (which is 
actually a correct behavior in this case, the pair of '(' is 
indeed the ')' ).  All the other interactions would be the same. 
If you put the cursor on the '}', Emacs would still show that it 
is a paren without a pair, just like now (but instead of saying 
that its "pair" is the '(', it wouldn't show anything, because '}' 
doesn't have a pair.

Why is it a desired thing that Emacs should show some mismatching 
paren if the cursor is on a completely unrelated paren?
