automatic semicolon insertion

[porten at froglogic.com]

Hi,

we received a report about a parse error that boiled down to be due to a
lack of yet another case of automatic semicolon insertion. Minimal test
case:

 { throw 1 }

Fixed by the attached patch.

Harri.

P.S. Is everyone from Apple subscribed to khtml-cvs ? All our commits are
cc'ed there. Would make sure that all our fixes can be picked up
automatically leaving this list for non-trivial changes to be discussed.

do automatic semicolon insertion after throw statements

Had to revert Helio's lexer.cpp change as I am using an older bison
than he is. It's more recent than the one that was causing problems for him
last time, though.
