EntryNodes ignored when UseEntryGuards==0, warning can be overlooked
The man page doesn't mention that the EntryNodes option only applies when Tor uses entry guards. I think this is not the expected bahaviour because the option is called "EntryNodes" and not "EntryGuards".
If you don't want to fix this, at least let Tor exit with an error when it reads the torrc file, because if someone provides a list of EntryNodes, that can only mean he doesn't want his computer to connect to other nodes, and it might be dangerous for him if Tor does it anyway.
