Feature request: make the sh-mode font-lock mode propertly highlight 
variables used in expression, such as:  (( var > 42 ))  $(( var++ ))

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I don't quite understand the request -- sh-mode doesn't font-lock
variables in other cases, so I don't quite see why it should font-lock
variables inside (( )) constructs?

 But it does? At least in `foo=bar` `foo` gets the
 font-lock-variable-name-face. At least to my understanding of "font-lock".

 But, I'm no really bothered by this, and wouldn't mind the issue being
 closed.

Sorry, don't know what I was thinking.

When $var++ is highlighted, then $(( var++ )) should be, too.
