Use comments rather than no-op string statements
Use comments rather than no-op string statements

This change replaces a few no-op string statements with regular
comments.  While there was no harm in the previous use of strings for
comments, this allows us to re-enable the corresponding pylint check
which may catch genuinely unintended cases.
