csh alias command

Is this some sneaky trick to drag some poor newbie into cross-posting to
"talk.bizarre", so you can roast him?

In any case, for those who are curious:

A quick look at the 4.3BSD C shell code indicates that aliases with only
one token aren't enclosed in parentheses, and those with more than one
token are.

	alias foo "foo -options"

has only one token, namely '"foo -options"'.

	alias foo foo -options

has two, namely 'foo' and '-options'.
