Problem: ins_str() is inefficient by calling STRLLEN() Solution: refactor ins_str() to take a length argument and let all callers provide the correct length when calling ins_str() (John Marriott) closes: #16711 Signed-off-by: John Marriott <basilisk@internode.on.net> Signed-off-by: Christian Brabandt <cb@256bit.org>
