vim-patch:7.4.530-531

Specify different kinds of counts for commands.
Updated ex commands generator scripts.

Includes fixes to comments from patch 7.4.531

Original message:

Problem:    Many commands take a count or range that is not using line
            numbers.
Solution:   For each command specify what kind of count it uses.  For
            windows, buffers and arguments have "$" and "." have a
relevant
            meaning. (Marcin Szamotulski)
