G.2.2.7 Environment variable %[format]-[argument] special text

%[format]-[argument] references the contents of an environment variable, e.g.:

The text `I am `%-USER '-user' will be expanded to
==> `I am `guest'-user', in case you logged-in as guest on your system.

This special text must always be trailed by a whitespace character which is removed in output!
