Re: old-menu-complete behavior in bash v4 / readline v6

By the way, if anyone wants a fix for this bug, here it is:

In lib/readline/funmap.c, around line 107, make "menu-complete" map to
rl_old_menu_complete:

{ "menu-complete", rl_old_menu_complete },

In lib/readline/complete.c, around line 2443, comment out the if-loop:

/*if (match_list_size > 1 && _rl_complete_show_all)
    display_matches (matches);*/

Then compile and install. Works great now.
