Adding escaping to CHAR: " -> CHAR: \"
...
It is not necessary to escape the " character, but it doesn't hurt and
is necessary for syntax-highlighting (FUEL) to work correctly.

02008979d9
factor: Change ERROR: foo ; to define ``throw-foo`` instead of having ``foo`` throw implicitly. The old ``foo`` still throws implicitly because this is a big change to get right in one patch, but it should be removed soon.

CREATE -> scan-new
CREATE-CLASS -> scan-new-class
