+
+	* mutt.h, muttlib.c: Allow format strings to be filtered. Any format
+	string ending in | will be expanded and piped through the first word
+	in the string. The string returned will be used for display. If the
+	returned string ends in %, it will be passed through the formatter a
+	second time. This allows the filter to generate a replacement format
+	string including % expandos.
