[PATCH 2/5] cli: move count to the new --exclude=(true|false|flag) naming scheme.

[Mark Walters <markwalters1009@gmail.com>]

Move the option --no-exclude to the --exclude= scheme. Since there is
no way to flag messages only true and false are implemented. Note
that, for consistency with other commands, this is implemented as a
keyword option rather than a boolean option.
