master c9d550a: Fontize $(...) slightly better in bash mode

branch: master
commit c9d550a301d3a5e62b3296804ccf42efc69d0796

    Fontize $(...) slightly better in bash mode
    
    * lisp/progmodes/sh-script.el (sh-font-lock-keywords-var): Fontize
    $(...) slightly better (bug#42417).  Instead of just fontizing the
    first word in the expression, fontize until the closing
    parenthesis.  This doesn't work well if you have nested $(...)
    expressions.
