Hi Jostein:

I just do:

emacs -Q /tmp/main.cs

Then pasted (or write) the code snippet shown in the example, and
re-indent the buffer:

I get this:

new myNamespace.myClass
{
    Name1 = 1,
        Name2 =2
        }

Exactly like in the example C-c C-o shows the same than in the
example. Even the fontification is wrong.

If I remove the dot like this myNamespacemyClass the fontification and
indentation is fixed immediately.

I am using the master branch (emacs-version = 30.0.50) tomorrow I can
try to reproduce the issue on emacs-29 branch, but I have to build it.

Best,
Ergus
