CC Mode 5.25 (C++); incorrectly inserts '//'

[Eric Hanchrow]

Dear Barry and Martin,

Here's how to repro the problem:

Start "emacs -q"

Type the following:

    C-x b ha RET
    M-x c++-mode RET
    M-x auto-fill RET
    ya M-( M-) { RET
    TAB goofy SPC << SPC "http://"; SPC << SPC hee SPC << SPC haw SPC << SPC 
margery SPC << SPC daw
    SPC << SPC yo SPC << SPC momma SPC << SPC wears SPC << SPC armyboots; RET
    }

You will see

    ya ()
    {
      goofy << "http://"; << hee << haw << margery << daw << yo << momma <<
                     //wears << armyboots;
        }

Note that the fourth line begins with the comment characters, "//",
which you didn't type, and which ought not be there.

Emacs should instead have displayed

    ya ()
    {
      goofy << "http://"; << hee << haw << margery << daw << yo << momma <<
               wears << armyboots;
    }
