sys.stdin.readline()

[Mike Maxwell]

I don't want to drag this out any longer.  Thanks to all the posters. 
Several mentioned that one-liners tend to both get re-used and to grow 
to multiple lines, and that that implied that maybe the notion of a 
one-liner was faulty.  This may be true, and I may find myself doing 
exactly what they suggest--building Unicode-aware versions of grep, sed, 
and tr (hopefully not awk :-)).  Time will tell.

Thank you also to Simon B. (simon at brunningonline.net) for pointing me to 
his one-liner implementation, which is much better than I {w|c}ould have 
done.
