Summary: For some reason, buck cython build starts to treat unprefixed strings as unicode strings. That breaks Mercurial where everything should be bytes. Therefore add the b prefix to make them byte strings explicitly. Reviewed By: DurhamG, ryanmce Differential Revision: D9015176 fbshipit-source-id: 7a3ef9d735362e3ae02208ec19d0551bf0adaaa4
