bug#43633: 28.0.50; Include definitions in glossary for: extensible, customizable, self-documenting, real-time display editor

[Jean Louis]

This is feature request or attempt to make Emacs more beginner
friendly:

When one goes into Info file, there is sentence:

Emacs is the extensible, customizable, self-documenting real-time
display editor.

In my opinion, those terms are special in Emacs, and should be
described as terms in the Glossary section of Emacs Info file.
