I figure a failed SIZE (returning 550 explicitly, since SIZE may not be
supported/working so we cannot assume a "good" response) should cause a
CURLE_REMOTE_FILE_NOT_FOUND unconditionally.

This seems related to KNOWN_BUGS #58, as if SIZE doesn't work (returning
something like 350) I believe libcurl won't return one of those errors anyway.
