arc browse seems to be broken for this install.
When using the Phacility copy, this command:
arc browse webroot/rsrc/externals/javelin/README
sends me to https://secure.phabricator.com/source/phabricator/browse/master/webroot/rsrc/externals/javelin/README, but when running against Phorge copy, it goes to https://we.phorge.it/browse/master/webroot/rsrc/externals/javelin/README and 404s.
