commit be505726b68d407a44fdcd9c7ac1ef722398532d
Author: João Távora <joaotavora@gmail.com>

    Fix electric-pair-tests by disabling bug#33794's fix with a variable
    
    The variable c--disable-fix-of-bug-33794, which should be removed in
    the short term in favor of a permanent solution, is introduced.
    
    It is bound to nil by default.  This means that breakage is still
    happening in actual c-mode and c++-mode usage, though the tests no
    longer show it.
    
    To get around this breakage, put
    
       (setq c--disable-fix-of-bug-33794 t)
    
    In your init file.  Evidently, you will lose the fix for bug#33794,
    but that only affects a small corner case of c-toggle-auto-newline,
    which is not turned on by default.
    
    See https://lists.gnu.org/archive/html/emacs-devel/2019-01/msg00360.html
    for more information.
