Here on Win32, I checked with gVim 7.0 and gVim7.2.218, and I get almost
the same:

[headline1]
Some Text (ere.
Some more text
Even more text

[headline2]
Some Text here.
Some more text
Even more text

After undoing, the buffer is not left modified.
And I typed the commands in (not using :normal).

Maybe the recursive gq is a problem?
