[hackers] [dwm][PATCH] Don't increase nmaster to larger number than current window count

This is resend. Ignore previous patch please.

It was annoying to me that whenever I pressed MODKEY+i more times than current window count (by holding it, for example), I had to undo that by pressing MODKEY+p to decrease nmaster, which could be avoided by limiting nmaster to window count. This patch should prevent this.
