Adding HGPLAIN to tramp's default environment

Adding HGPLAIN to tramp's default environment

[Jordi Gutiérrez Hermoso]

Tramp was freezing for me when checking vc-registered on my remote hg
repos. Turns out my remote hg config was the problem, probably the
pager. As suggested by the hg docs,

$ hg help env.hgplain
    HGPLAIN
        When set, this disables any configuration settings that might change
        Mercurial's default output. This includes encoding, defaults, verbose
        mode, debug mode, quiet mode, tracebacks, and localization. This can
        be useful when scripting against Mercurial in the face of existing
        user configuration.

        Equivalent options set via command line flags or environment variables
        are not overridden.

Hence the following patch.

Thanks.  I think this should be handled in vc-hg.el, tho.

That's also my belief. I'll check in a couple of days, when time
permits. But I won't object if somebody beats me :-)

For the records, there is now bug#18940 in debbugs about the same
problem. I propose to continue the discussion there.
