chg and the schemes extension

[Marc Simpson]

Hi all,

I encountered some unexpected behaviour with chg this morning:
It seems that once the command server is running, schemes added to
~/.hgrc are not recognised by chg.  For example, given the following
minimal configuration:

    [extensions]
    schemes =

    [schemes]
    foo = http://foo.example.com/repos/

hg and chg output expand the foo scheme equivalently (this is the
first chg run, so the command server is started):

    $ hg debugexpandscheme foo://baz
    http://foo.example.com/repos/baz

    $ chg debugexpandscheme foo://baz
    http://foo.example.com/repos/baz

Subsequently adding a second scheme to ~/.hgrc demonstrates the issue:

    [schemes]
    foo = http://foo.example.com/repos/
    bar = http://bar.example.com/repos/

where 'bar' is expanded as expected by hg, but not chg:

    $ hg debugexpandscheme bar://baz
    http://bar.example.com/repos/baz

    $ chg debugexpandscheme bar://baz
    bar://baz

Is this known behaviour (and working as designed)?  The above was
tested in 5.3.

Thanks,
Marc
