[joe] Syntax highlighter balanced delims problem

[Andy T. <tu...@mi...>]

When one uses save_c and the checks for a match using &, usually & just
matches the saved character.  But there are special cases for the beginning
of paired characters, like "(", "[", etc.  The problem is that joe thinks
that "`" is the start of a paired character (paired with "'") but Perl does
not.  This is a reasonable thing to think for some other languages (like
M4).

I can see two ways to deal with this.

1) Change nothing.  Make special cases in the jsf files for "`". 
Advantages: Don't have to make the highlighting language any more complicated.
Disadvantages: Special cases mean lots of extra states.

2) Add a special char like "&" that just matches what save_c saved and
doesn't try to find the other part of a pair.
Advantages: Languages that don't use the "`'" pair have significantly
simpler jsf files.
Disadvantages: Syntax highlighting language gets more complicated.


Adding a work around for "`" to the existing Perl jsf file increases its
size by about 36 lines.  If the work around seems like the way to go then
I'll post a patch that includes it.
