-;;; Indenting of some tasking constructs is still buggy.
-;;; -------------------
-;;; package Test is
-;;; -- If I hit return on the "type" line it will indent the next line
-;;; -- in another 3 space instead of heading out to the "(". If I hit
-;;; -- tab or return it reindents the line correctly but does not initially.

-;;; Nothing_To_Wait_For_In_Wait_List);
+;;; Character constants with otherwise syntactic relevant characters
+;;; like `(' or `"' throw indentation off the track. Fontification
+;;; should work now in Emacs-19.35
+;;; C : constant Character := Character'('"');
