  strmov(dst, src) moves all the  characters  of  src  (including  the

  closing NUL) to dst, and returns a pointer to the new closing NUL in

  dst.	 The similar UNIX routine strcpy returns the old value of dst,

  which I have never found useful.  strmov(strmov(dst,a),b) moves a//b

  into dst, which seems useful.
