Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

cc-mode tries to be smart and adds newlines to a file without
informing the user and without any easily found option to suppress it.

You can check it easily (see also recent input below): Start emacs
with "-q --no-init", create a new file "test.c", add some text without
a trailing newline and save the file. Then a newline is silently added.
I couldn't find a possibility to suppress this.

In my opinion this behaviour is unacceptable. If for some reason I
choose to create a file with no trailing newline, it is not emacs's
business to change the file silently behind my back.
