NAME
	true_strlen - Calculates the true length of a string even if
	colour codes (^<letter>) have been added.

SYNOPSIS

	int true_strlen(char *s);

DESCRIPTION

	The true_strlen() function calculates the length of a string taking
	into account colour codes which are present. A string of "hello"
	would return 5 with strlen() and 5 with true_strlen(), but a
	string of "^Rhello^N" would return 9 with strlen() rather than,
	the correct, 5 with true_strlen (the ^R and ^N are converted into
	colour codes which do not take up any extra characters on output)

	The terminating '\0' character is not included in the count as
	with strlen().

RETURN VALUE

	true_strlen returns the number of visible characters that will
	be shown to the person on the talker.

SEE ALSO

	strlen, string(3).

BUGS

	No known bugs but there is some code repetition which could
	be cleaned up.
