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

1747 calculates the visible width of a color coded string.
1749 *valid is filled with TRUE if the string is a valid colored string (that is, if
1750 it does not end with an unfinished color code). If it gets filled with FALSE, a
1751 fix would be adding a STRING_COLOR_TAG at the end of the string.
1753 valid can be set to NULL if the caller doesn't care.

1756 all characters until the zero terminator.

1820 escape_carets is false, the function will just strip color codes (for logging
1823 If the output buffer size did not suffice for converting, the function returns

1825 strlen(str)+1 bytes, and if escape_carets is true, it can need strlen(str)*1.5+2
1826 bytes. In any case, the function makes sure that the resulting string is
