Hey again Tom.

About mercurial/hg.

While as far as I know there hasn't been a mercurial tree
for the linux kernel sources in many years, I believe the
mercurial command to list files should be different.

I think this should be

	"list_files_cmd" => "hg manifest -R \$file",

It seems to work on a XEN test branch but does anyone
really care about hg support in get_maintainers?

btw: to the XEN maintainers

The XEN mercurial branch for MAINTAINERS has a few odd
entries and a few missing file patterns

I think the XEN MAINTAINERS file should be updated to:
