New description:

 For downloads and uploads that fail because too few servers are connected,
 we should report that rather than reporting a problem with the specific
 file.

 k may differ between files in the case of downloads, but if we find ~~no~~
 less than k shares and fewer than the configured {{{shares.needed}}}
 servers are connected, then the failure to find shares is probably due to
 lack of servers. For uploads to succeed, at least {{{shares.happy}}}
 servers must be connected.
