The bitmap\ncode is going into v2.0, but there should be nothing (not even\ndocumentation) in v1.9.2. I don't know how the msysgit folks build their\ndocumentation, but I wonder if it accidentally built from current\n'master' rather than v1.9.2.\n\nYou might get more information at the msysgit mailing list:\n\n  https://groups.google.com/forum/#!forum/msysgit\n\n-Peff\n"}]}
