The change was made intentionally. Historical versions of sh ignore (or
more precisely reset) the loop state when entering a shell function, so
the continue doesn't have any effect. Posix doesn't say anything specific
about it, but it doesn't call out a change from the historical behavior,
so it came up reported as a bug.
The discussion about the change took place on the dash mailing list,
but the gmane.org archives are down right now so I can't give you a URL.
