Merged r17061 from trunk to 3.2-stable (#27516)

mercurial: separate command options and positional arguments with "--"

We don't have much problems here thanks to hgtarget(path) and CGI.escape(),
which prepends a repository path and encodes "=" character respectively, but
it's better to not rely on the side effect of these functions.
