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,
