portage.manifest: Fix mis-parsing Manifests with numerical checksums Fix the regular expression used to parse Manifests not to fail horribly when one of the checksums accidentally happens to be all-digits. The previously used regular expression used to greedily take everything up to the first number as filename. If one of the checksums happened to be purely numeric, this meant that everything up to that checksum was taken as filename, and the checksum itself was taken as file size. It was also capable of accepting an empty filename. The updated regular expression uses '\S+' to match filenames. Therefore, the match is terminated on first whitespace character and filenames can no longer contain spaces. Not that it could ever work reliably. Spotted by Ulrich Müller.
