Epsilon anyone?

I really don't care (honestly) but a null word can be considered a word too!

In yacc-like terms:

wordlist:
        | wordlist WORD
        ;

It doesn't really matter until one considers perverse abuses of
a shell, such as those embedded in a Makefile somewhere.

FreeBSD's shell (and ksh93) both perform "correctly" IMHO and
wouldn't make the change.  I'm also not likely to declare a
Jihad against such a change either  :-)

It doesn't hurt anything the way it is and represents a better
generalization (IMHO again).

Cheers,
