Well, ok, let's face on C99. I changed things as follows: the
Client struct looks like before. However I kept the static
initialization of ntags, seltags and the newly introduced
prevtags. This means that third-party patches may access any
variable except the latter ones (actually I see no reason why
you want to access seltags, prevtags or ntags from a patch). The
tagging approach is quite central to dwm and needs no additions
in my opinion.

Instead of looping for tags initialization in Client->tags I use
memcpy from now on.

See latest patch for further information and let me know any
bugs if you encounter them. Otherwise dwm-4.6 is on its way.
