;; Mark a `#' character as having punctuation syntax in a variable reference.
'(("\\$[({]?\\(#\\)" 1 (1 . nil))))
;; Really we should do this properly. From Chet Ramey and Brian Fox:
;; "A `#' begins a comment when it is unquoted and at the beginning of a
;; word. In the shell, words are separated by metacharacters."
;; To do this in a regexp would be slow as it would be anchored to the right.
;; But I can't be bothered to write a function to do it properly and
;; efficiently. So we only do it properly for `#' in variable references and
;; do it efficiently by anchoring the regexp to the left.
