Lexer again.

Sorry, guys. Here is the ultimate patch which keeps the entire
behavior as it was, apart from forbidding minus-terminated 
operators. Seems that I have to break the habit of doing before
thinking properly :-/  The point is that my second patch breaks
constructs like a & b  or   a ! b. This patch is to be applied 
instead of any of two other today's patches.

Hey! Later discussion on that matter made us think that minus-terminated
operators have to be preserved, especially considering
that there is already one such operator here: geometric ?-.
I'm terribly sorry, but that patch shouldn't be applied.

The other patch applied by you which exterminates uminus exclusive
state in parser is considered to be ok.

He knows he'll never have to answer for any of his theories actually
being put to test. If they were, they would be contaminated by reality.
