[wmii] new colmode syntax

[Suraj Kurapati]

Hello,

I noticed some new colmode syntax in wmii-hg:

  default-max   (was: default)
  stack-max     (was: stack)
  stack+max     (was: max)

What is the rationale behind this change?
To support arbitrary combinations of colmodes?

IMHO, this change introduces needlessly complexity;
the old, single-word colmodes were sufficent.

Thanks for your consideration.
