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!
