Fix method doc signatures for multiline required parameters (#374)

* Fix method doc signatures for multiline required parameters.

Existing doc generator failed to recognize parameters as required when parameter descriptions
extended over more than one line. Besides presenting incorrect information, resulting
inconsistencies broke checks for automated sample generation.
