    Refactoring julia-char-regex as an rx form.
    
    This regexp has been simplified from the original. The equivalent rx
    form of the original is:
    
    (defconst julia-char-regex
      (rx (submatch (or (any "-" ";" "\\" "^" "!" "|" "?" "*" "\\" "<" "%" "," 
"=" ">" "+" "/" "&" "$" "\\" "~" "\\" ":")
                        (syntax open-parenthesis)
                        (syntax whitespace)
                        bol))
          (submatch "'"
                    (submatch (or (submatch (*\? (not (any "'"))) (not (any 
"\\" "\\")))
                                  (submatch "\\\\")))
                    "'")))
    
    However, the inner groups are unnecessary and there are repeated "\\"
    occurrences.
