That's correct.  I have a note from 2001 regarding vim, and seem to
recall some discussion about making vile do this, suggesting that it
would be possible to use the syntax coloring information to limit the
choices of fence matching.  (I'd have to dig into vim's code, but my
recollection was that its behavior was hardcoded, assuming C language
syntax -- Perl can be a bit harder).
