bug#27079: 24.4; clipboard paste introduces whitespace in Fundamental (not in Lisp Interaction)

[James Powell]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

* Test
1. cat useful-repro-clipboard-fail-2017-05-25.txt (attached) in a 
gnome-terminal window.
2. select lines from it, e.g.
   :  16809:            record(locid="1066", value=0)
   :    18892:            record(locid="1067", value=0)
   :    21094:            record(locid="1071", value=0)
3. In the same window (or another new one, doesn't matter) run "emacs -Q -nw".
4. right click to paste.  Observe the few lines you selected appear in the 
*scratch* buffer,
         faithfully reproduced.
5. C-x b asdf <enter>
6. right click to paste.  Observe the introduction of unwanted whitespace,
         as in
   :   16809:            record(locid="1066", value=0)
   :      18892:            record(locid="1067", value=0)
   :              21094:            record(locid="1071", value=0)
* What I expect to happen
In step six of the test, the numbers should all be in a neat column.

15 matches for "record(" in buffer: myappi5q7Zo                                 
   3686:            record(locid="970", value=0)
   6624:            record(locid="973", value=0)
   9392:            record(locid="1061", value=0)
  12225:            record(locid="1062", value=0)
  14571:            record(locid="1065", value=0)
  16809:            record(locid="1066", value=0)
  18892:            record(locid="1067", value=0)
  21094:            record(locid="1071", value=0)
  23293:            record(locid="1073", value=0)
  25577:            record(locid="1086", value=0)
  27647:            record(locid="1101", value=0)
  29927:            record(locid="1102", value=0)
  32273:            record(locid="1114", value=0)
  34467:            record(locid="1125", value=0)
  36476:            record(locid="1126", value=0)

* What happens instead
In step six of the test, the numbers get indented, line after line,
each more indented than the next.
* Due diligence
I can reproduce this with the built-in Debian 8 emacs (emacs24 -
24.4+1-5, GNU Emacs 24.4.1)

Summary

|   version | repro | host     |
|    23.3.1 | no    | research |
|      24.3 | no    | pliny    |
|    24.3.1 | no    | gaia     |
|    24.5.1 | yes   | pliny    |
| 24.5.50.1 | yes   | pliny    |

Buffer *scratch* is in Lisp Interaction mode, buffer asdf is in Fundamental.
This seems to make the difference.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
                For information about debugging Emacs, please read the file
                /usr/share/emacs/24.4/etc/DEBUG.
