bug#5490: 23.1.91; CC Mode, after a while, everything is topmost-intro.

[Jan Djärv]

Hello.

This is one of those vague bug reports that aren't easy to reproduce.
After using Emacs for some time (several hours, more than 4) and editing
many C++ and C files, indentating breaks down.  This manifests itself
that most lines get indetated at column 0.  Doing C-c c-s on those lines
shows topmost-intro.  even if they should be inclass or statement.

Restarting Emacs fixes everything.
