patterns can be reconfigured with AutomapHostsSuffixes.
- If Tor is invoked from something that isn't a shell (e.g. Vidalia),
now we expand "-f ~/.tor/torrc" correctly. Suggested by Matt Edman.
- Treat "2gb" when given in torrc for a bandwidth as meaning 2gb, minus 1
byte: the actual maximum declared bandwidth.
o Removed features:
- Removed support for the old binary "version 0" controller protocol.
