extensions help: make disabling example analogous to enabling example The example for enabling an extension in the module search path is: foo = foo can only be disabled by: foo = ! and not by: hgext.foo = ! As the examples now omit "hgext." the example hgext.bar = ! is misleading.

test-help: improve test coverage Adds a test for using the help option with the version option. Extends test coverage of commands.help_ by another 2 lines.

setup: ignore 'not importing' warnings during version detection Python will issue an ImportWarning when seeing 'import locale' if there is a locale/ directory present without a __init__.py file. The warning is silent by default, but it somehow shows up anyway on Windows when setup.py executed hg. The warning causes runcmd to panic since it sees output on stderr. This patch ignores warnings on stderr about not importing a package.

tests: load with "ext =" instead of "hgext.ext ="
