bug#24618: 26.0.50; `condition-case' doesn't allow catching all signals

From: Philipp Stephani
Subject: bug#24618: 26.0.50; `condition-case' doesn't allow catching all signals
Date: Tue, 04 Oct 2016 18:42:27 +0200

Consider the following code:

(condition-case err
    (signal 'does-not-exist '(1 2))
  (error (print err)))

The signal is not caught by condition-case because it has no error
conditions.  This makes it impossible to reliably catch all signals
(without abusing the debugger).  I propose that an error condition of
't' in `condition-case' should be interpreted as 'all conditions'.
