Subject: If the fetcher reported success and the file is too small, don't attempt to resume... 
X-Git-Tag: v2.2_pre1~984
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=203ec4fdc3ef654ba93eb5a6db912a031cbd3314;p=portage.git

If the fetcher reported success and the file is too small, don't attempt to resume.  Upstream probably changed the distfile and we need to show a digest verification failure so the user gets a clue.
