Bill Currie eae11661e4 strncat parameter audit. Unfortunatly, strncat is counter-intutite: the n in 
strncat is not the maximum length of the destination string, but of the SOURCE
string, thus strncat (dest, src, sizeof (dest)) is incorrect. It should be
strncat (dest, src, sizeof (text) - strlen (dest)). Even then, no terminating
nul will be written if src is too long, but at least it won't crash the stack:)
