The bzr.dev branch seems to have:

liw at gytha$ ~/bzr.dev/bzr.dev/bzr help global-options
Global Options

These options may be used with any command, and may appear in front of
any
command.  (e.g. "bzr --quiet help").

--quiet        Suppress informational output; only print errors and
warnings
--version      Print the version number

--no-aliases   Do not process command aliases when running this command
--builtin      Use the built-in version of a command, not the plugin
version.
               This does not suppress other plugin effects
--no-plugins   Do not process any plugins

--Derror       Instead of normal error handling, always print a
traceback on
               error.
--profile      Profile execution using the hotshot profiler
--lsprof       Profile execution using the lsprof profiler
--lsprof-file  Profile execution using the lsprof profiler, and write
the
               results to a specified file.

Note: --version must be supplied before any command.
liw at gytha$

Personally, I think it would be good to list those global options that
are not related to development of bzr itself in the option listing for
each command. Better discoverability.
