parsergen - adjust for recent scanner fix.
scanner was recently fixed to correctly skip over C code with
a string immediately after a '(', so we can remove the extra
spaces we inserted before.
For this to work, we need to stop ignoring TK_String

scanner: don't allow an unknown mark to run into a string or comment
This means that e.g.
printf("hello")
where no marks are declared will not treat
("
as an known mark, but instead find
(
and then a string.
This is important for skipping over C code in 'parsergen'.

scanner: initialise token state properly.
We need to call do_strip() at the start to ensure the correct
col and indent is used for the first token.
