671 (a space) so the routine knows how long a space is.

1744 calculates the visible width of a color coded string.
1746 *valid is filled with TRUE if the string is a valid colored string (that is, if
1747 it does not end with an unfinished color code). If it gets filled with FALSE, a
1748 fix would be adding a STRING_COLOR_TAG at the end of the string.
1750 valid can be set to NULL if the caller doesn't care.

1753 all characters until the zero terminator.

1816 If escape_carets is true, the resulting string will be safe for printing. If
1817 escape_carets is false, the function will just strip color codes (for logging

1821 FALSE. Generally, if escape_carets is false, the output buffer needs
1822 strlen(str)+1 bytes, and if escape_carets is true, it can need strlen(str)*1.5+2
1823 bytes. In any case, the function makes sure that the resulting string is
