Command word post-assignment doesn't get highlighted as unknown-token

[danielshahaf]

x=y foobar should highlight foobar as unknown-token, but doesn't.

fixes it but fails one test:

Running test brackets
Running test main
# assign-semicolon
1..2
not ok 1 - [4,4] «;» - expected "commandseparator", observed "unknown-token".
ok 2 - [6,9] «echo»

That test is about x=y; ls being valid. I think it needs a new state: an assignment may be followed by either a command word or a command separator (or a redirect operator, of course) but not by a non-command word.

Works in master. Regression test added in bd9094c.
