Attempt #3, adding a new command 'sfilter'

[Maxim Sobolev]

Why not just write simple 5-line script in your favorite scripting 
language (perl, python, ruby etc) that does just this and forget about 
it? I don't think performance is really a concern here since the most 
time this program will spend waiting for the I/O anyway, so that doing 
it in C makes little or no sense.

IMHO this is one of the reasons we do have all those lightweight 
languages around - to avoid having separate utility and/or command line 
option for each and every particular situation.
