[Lars Ingebrigtsen]

branch: master
commit dbec115948657d4f0b5c8ad86410b8e1c9e825d2
Author: Daniel Martín <mardani29@yahoo.es>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Fix instrumented eval-defun not printing "Edebug:" to the echo area
    
    * lisp/progmodes/elisp-mode.el (elisp--eval-defun): Determine if we're
    instrumenting a function and call eval-region with PRINTFLAG set to
    nil if so (Bug#50245).
    
    * test/lisp/progmodes/elisp-mode-tests.el
    (eval-defun-prints-edebug-when-instrumented): Add a new test.
