/* File : strmake.c
Author : Michael Widenius
Updated: 20 Jul 1984
Defines: strmake()
strmake(dst,src,length) moves length characters, or until end, of src to
dst and appends a closing NUL to dst.
Note that if strlen(src) >= length then dst[length] will be set to \0
strmake() returns pointer to closing null
