The current code does something predictable as well: any number that
is not a positive number of colors and not -1 means the same as zero,
i.e. switch to the default number of colors, the one specified by the
terminal's termcap/terminfo entry. (The code that does that is in
tty_setup_colors.)
Thus,
emacs -nw --color=2000
and
emacs -nw --color=-2000
produce the same result. What you suggest will change that.
Do you think that negative arguments are ``special'' in the sense that
they imply that the feature is to be turned off?
(I should also add that the user is not supposed to use numbers as
arguments to the --color option, except if she specifies the number of
supported colors, like --colors=8 or --colors=256. That is, I never
meant for them to say --colors=-1 or --colors=0, since the expected
effect of --colors=0 might be to turn off the colors, which is not
what happens. Similarly, --colors=-2000 was not something I expected
users to say.)
