Commands 'M' and 'Ctrl-m' not working properly

[klartext]

release 26:

'M' does not invert the marks - it seem to have no effect at all
'Ctrl-m' does not remove all marks - it inverts the marks

The manpage says:

 m      Mark/unmark the current image.
 M      Reverse all image marks.
 Ctrl-M Repeat last mark action on all images from the last marked/unmarked up to the current one.
 Ctrl-m Remove all image marks.

Hi, see config.def.h

        { 0,            XK_m,             g_toggle_image_mark,  None },
        { 0,            XK_M,             g_mark_range,         None },
        { ControlMask,  XK_m,             g_reverse_marks,      None },
        { ControlMask,  XK_u,             g_unmark_all,         None },

More accurate manpage:

       m      Mark/unmark the current image.

       M      Repeat last mark action on all images from the last
              marked/unmarked up to the current one.

       Ctrl-m Reverse all image marks.

       Ctrl-u Remove all image marks.
