morning.
a few years ago the strcpy.3 page got split in order to create the
strncpy.3 page. the EXAMPLES section went to that page, so i'm guessing
that's where the reference should lie. it's a tough kind of thing to
check when you make such changes.
diff below. i'll commit it shortly if i don;t hear otherwise.
