bug#23785: Emacs 25: 'Undo' overdoes things.

[Lars Ingebrigtsen]

This was a pretty long bug report with many suggested patches, some of
which were applied and then reverted.

But this one was applied and is still in Emacs:

commit c98bc9821f4a402d5fda67fe141ed34622c50e4f
Author:     Phillip Lord <phillip.lord@russet.org.uk>
AuthorDate: Fri Jun 17 22:34:50 2016 +0100

    Ensure undo-boundary after all commands
    
I may be misreading the thread, but it sounded like this fixed the
reported problem?  So I'm closing this bug report; if there's more to be
worked on there, please respond to the debbugs address and we'll reopen.
