Philipp Stephani 53dfd85a7f Edebug: Disable backtracking when hitting a &define keyword. 
Edebug doesn't deal well with backtracking out of definitions, see
Bug#41988.  Rather than trying to support this rare situation (e.g. by
implementing a multipass parser), prevent it by adding an implicit
gate.

* lisp/emacs-lisp/edebug.el (edebug--match-&-spec-op): Disable
backtracking when hitting a &define keyword.

* test/lisp/emacs-lisp/edebug-tests.el
(edebug-tests-duplicate-&define): New unit test.
(edebug-tests--duplicate-&define): New helper macro.

* doc/lispref/edebug.texi (Backtracking): Mention &define in the list
of constructs that disable backtracking.

* etc/NEWS: Document new behavior.

README 

This directory contains source code for the parts of Emacs that are
written in Emacs Lisp.  *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions.  Byte-compiled
files are architecture-independent.

The term subdirectory contains Lisp files that customize Emacs for
certain terminal types.  When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.

The other subdirectories hold Lisp packages grouped by their general
purpose.
