Add support for "classic" coding style - detect tokens in PROCEDURE DIVISION terminated by a period.

[neopragma]

Currently strips off periods. This causes problems for certain Cobol statements because there is no way to detect the end of a statement.

It handles this:

CALL 'SOMETHING'
USING ONE TWO THREE
END-CALL

It does not handle this:

CALL 'SOMETHING'
USING ONE TWO THREE.
