/* Format VALUE for use as the length indicatior of an S-expression.
The caller needs to provide a buffer HELP_BUFFER wth a length of
HELP_BUFLEN. The return value is a pointer into HELP_BUFFER with
the formatted length string. The colon and a trailing nul are
appended. HELP_BUFLEN must be at least 3 - a more useful value is
15. If LENGTH is not NULL, the LENGTH of the resulting string
(excluding the terminating nul) is stored at that address. */
