It is required for removing non-existing files from the result of
the brace expansion.

For example, under SunOS 5.7:

Z(2):akr@is27e1u11% print -l /usr/{lib,{{X11R6,openwin},local{,/X11{,R6}}}/lib}/X11/rgb.txt
/usr/lib/X11/rgb.txt
/usr/X11R6/lib/X11/rgb.txt
/usr/openwin/lib/X11/rgb.txt
/usr/local/lib/X11/rgb.txt
/usr/local/X11/lib/X11/rgb.txt
/usr/local/X11R6/lib/X11/rgb.txt
Z(2):akr@is27e1u11% print -l /usr/{lib,{{X11R6,openwin},local{,/X11{,R6}}}/lib}/X11/rgb.txt(N)
/usr/openwin/lib/X11/rgb.txt
Z(2):akr@is27e1u11% 

So, $(<$files[1]) causes an error if (N) is not used.

Also, I suppose that (N) was intended by Sven because
Completion/User/_cursors use same method for cursorfont.h.
