[dwm] patch: make togglemax() work in tiled layout

[Peter Hartlich]

Hi,

In case anyone has use for it, the attached patch against hg tip
will make togglemax() work in the tiled layout by first toggling
the window's floating status and then restoring it later.

Beware though that I am not a C programmer.

Regards,
Peter
