+       * src/{proto.h,global.c,text.c}: Keep a pointer to the Uncut item in
+       the functions list, to be able to change its description to Unjustify
+       at the appropriate moment.  This avoids having to fully repopulate
+       the functions and shortcuts lists before and after every Justify.
+       Also, look for ^U only in the main menu, to which ^W M-J factually
+       returns and which shortcut_init() "sneakily" sets.

        * src/global.c (shortcut_init): Limit M-T (cut-till-end-of-file) to
        the main menu, and M-J (full-justify) to the main and search menus.
