But, I view the pipe symbol (and others like it) as a separator, too. I
realize I'm being picky, here, but I don't see this as an `obvious' place for
whitespace.
If we use |, and require whitspace, then
ls -l usr:big/ole/dir|more
and
ls -l usr:big/ole/dir | more
are two completely different fish kettles. Confusion reigns. I like
ls -l usr:big/ole/directory->more (which = ls -l usr:big/ole/dir -> more)
much better, and since it builds on previous syntax, I don't think it's
overkill.
