Ugh. It doesn't matter how careful i try to be. Here's a (hopefully)
unmangled version:
(defvar underline-by-font-lock-delimiter "_")
(defvar underline-by-font-lock-flag nil)
(defun toggle-underline-by-font-lock (delimiter)
"Toggle font-lock-based underlinging of text between DELIMITER.
Simultaneusly make the string DELIMITER itself invisible.
Default delimiter defined by `underline-by-font-lock-delimiter'."
(interactive "P")
(let* ((delim (if delimiter
(read-string "Delimiter: ")
underline-by-font-lock-delimiter))
(delim-regex
(concat "\\(" delim "\\)\\([^" delim "]*\\)\\("
delim "\\)\\(.\\)")))
(funcall (if underline-by-font-lock-flag
#'font-lock-remove-keywords
#'font-lock-add-keywords)
nil
`((,delim-regex
(1 '(face nil invisible t))
(2 'underline)
(3 '(face nil invisible t))
(4 'default))))
(setq underline-by-font-lock-flag
(not underline-by-font-lock-flag))
(font-lock-fontify-buffer)))
