bug#5530: Emacs 23.1 "ESC C-q" behaves badly ; Emacs 21.2 works Ok

Indenting region does different indenting from indenting line in Emacs 23.1.
Works nicely in Emacs 21.2.

 

1) Save the attached file as "Foo.cpp", or cut and paste below code into
"Foo.cpp".

 

2) Visit "Foo.cpp" in Emacs 23.1 (no .emacs file required)

 

3) Get into c++ mode:

     ESC-m c++-mode

 

4) Put cursor on '{' at line 2 and indent the region:

     ESC C-q (c-indent-exp)

 

     Observe the "};" at line 23 now appears in column 1.

 

5) Now move cursor to "}' on line 23 and indent line:

    TAB (c-indent-line-or-region)

 

   Observe the "};" on line 23 moves to column 3.

 

Repeat of 4 and 5 causes the "};" on line 23 to shift between column 1 and
column 3.

The "};" should always be in column 3 and not shift to column 1.  Emacs 21.2
works correctly.

 

Also note 21.2 indents line 22 ">::Result" to line up with the "typedef" of
line 18 which in my opinion is nicer!
