[dwm] clientspertag status message

[Ritesh Kumar]

Hi,
    I am new to the list, so hi again :)
    I developed a small patch for dwm with pancake's clientspertag to
show if clientspertag is active. This basically adds additional status
text of the form '{n}' to the current status text where n is the
number of clientspertag currently active.
    However, I think a flexible way to show status messages could be
used by additional patches to show some textual data on the dwm status
bar. clientspertag seemed like a good candidate but I don't know about
any others. I was curious to know what you guys think.
     And thanks for developing dwm... its truly wonderful :)
