do not trust FileFd::Eof() in pkgTagFile::Fill()
The Eof check was added (by me of course) in 0aae6d14390193e25ab6d0fd49295bd7b131954f as part of a fix up ~a month ago (at DebConf). The idea was not that bad, but doesn't make that much sense either as this bit is set by the FileFd based on Actual as well, so this is basically doing the same check again – with the difference that the HitEof bit can still linger from a previous Read we did at the end of the file, but have seek'd away from it now. Combined with the length of entries, entry order and other not that easily controllable conditions you can be 'lucky' enough to hit this problem in a way which even visible (truncating of other fields might not be visible easily, like 'Tags' and others). Closes: 723705 Thanks: Cyril Brulebois
