Subject: bug#25150: 26.0.50; sexp motion commands don't work reliably in message-mode
Date: Fri, 09 Dec 2016 12:18:45 -0800

Starting from "emacs -Q":

Open a new buffer.

M-x message-mode.

Enter the following two lines of text:

{"":[
]}

Press C-M-b (backward-sexp).

Point should move to the opening brace, but instead it moves to the opening square bracket.

Move point to the opening brace and press C-M-f (forward-sexp).

Point should move to the closing brace, but an "unbalanced parentheses" error is raised instead.

If the two lines are joined:

{"":[]}

...then both commands work as expected.

If you enter the two-line text above and THEN enter message-mode, the two sexp motion commands work as expected.  But if you then enter any additional single character in the buffer, the commands behave incorrectly again, as described above.
