+/*  File   : strend.c
+    Author : Richard A. O'Keefe.
+    Updated: 23 April 1984
+    Defines: strend()
+
+    strend(s) returns a character pointer to the NUL which ends s.  That
+    is,  strend(s)-s  ==  strlen(s). This is useful for adding things at
+    the end of strings.  It is redundant, because  strchr(s,'\0')  could
+    be used instead, but this is clearer and faster.
+    Beware: the asm version works only if strlen(s) < 65535.
