Issue 5656: Warn about accessing the Global context explicitly (issue 567050043 by address@hidden)

[thomasmorley65]

I know several custom codings (defining a new grob, thus the need to
reintroduce all-grob-descriptions at Global level) using

\layout {
  \context {
    \Global
    \grobdescriptions #all-grob-descriptions
  }
}

will this be disallowed with this patch?
Then I'd object.

If it stays allowed, why disallow \context Global etc then?
