Thanks, that's better than what we had in 2.18, but I'm afraid it's 
still too complicated, in that it intrudes fgrep and egrep 
implementation into grep proper.  We need separation of concerns, where 
one can maintain 'grep' without having to worry about 'fgrep'.  The 
current shell script does that, as would a simple C file whose main 
function uses execlp to run the grep executable.  But I expect that any 
changes along these lines can wait until after 2.19 is out (as can some 
other cleanups and speedups that I have saved up...).
