Use "continue" instead of "break" to clarify loop flow.
When dropping tokens, the switch case had a "break" to document the intended
no-op on that branch. Often a break-only case clause is an erroneous attempt to
exit an enclosing loop, so linters flag it.
Without change of behaviour, use "continue" instead.
