+;; New 2.4 ordrules supports regexps with start-anchored matches.
+;; Thus we can activate the leading blank processing rule. The
+;; parenthesis-discard rule must trigger everywhere, not just at the
+;; start of the index key.
+;; The blank suppression clause got optimized, it now triggers only
+;; if there are multiple blanks and not for each appearing blank.

;; Support handling of some common macros for logos; ignore all other
;; TeX commands.
