[dwm] 3.8: incnmaster bugfix

Hi,

I fixed a small bug in incnmaster: there was no check if nmaster matches
the maximal number of clients of the current tag.
No it behaves better, but it fails partially if tags have different number
of clients. The only way to fix it completely is the combination with
dfenze's 'Layout per tag - patch' (but I didn't test it).

Here is it:

diff -r 2dec35ad6703 layout.c
--- a/layout.c Mon Mar 05 11:54:59 2007 +0100
+++ b/layout.c Thu Mar 22 20:05:15 2007 +0100
