Yeah, it becomes more clear in patch 2, where the value can be either
"31" or "91", for the bright or non-bright variant, and adding "30" is
wrong. (But certainly I agree this needs to be explained here).

Another way to write it would be to store 0-7 in the value as before,
and then add a separate "bright" flag to "struct color". And then the
output becomes:

  COLOR_FOREGROUND_OFFSET + c->value + (c->bright ? COLOR_BRIGHT_OFFSET : 0)

or similar. One minor confusion there is that COLOR_256 and COLOR_RGB
would ignore the "bright" field.
