Complete aliases that expand to a shell escape

mike/mgsh

`alias ll '!ls -la'` makes everything after `ll` a shell argument just as
surely as typing the `!` does, but Tab there still went to the builtin
command tree and found nothing. The dispatch now asks what a line will
turn into rather than how it starts: a '!' escape, or a name that is not a
builtin and resolves to an alias whose body starts with '!'.

Only the arguments complete — the command word is fixed by the alias
body, so `ll vi` offers the file, never the editor. An alias to a builtin
stays with the builtin tree.

Only the alias itself is inspected, not what its expansion might expand
to in turn: an alias chain can rewrite its own arguments, and guessing at
that would offer candidates for a command line other than the one being
built.
