[gentoo-portage-dev] [PATCH] emirrordist: Report all stat() errors instead of first one

[Michał Górny]

When DeletionIterator fails, report all stat() errors.  Reporting
just the first one results in confusing logs, suggesting that one
of the location did not exist but the other existed and was removed.
