Hi,

Well.. it was not unnecessary. The code was actually unreadable, wrong indentations and inconsistent throughout the whole file.
I needed to execute this auto-formatter, before I could even begin to understand the code.

In fact, I urge you to execute this on the whole archive. And keep the code quality high via a CI pipeline or something.

I can understand it makes it hard to read. I also fixed other some issues like this double error message during login and all the debug statements.
What would be your approach? I think it's still wise to auto-format the code in consistent matter.

Regards,
Melroy van den Berg

> Thanks for working on X2Go Client. With your patch, there is a problem though. It is barely unreviewable, because you have so many changes (also white space changes) in one patch file.
>
> Please clone the X2Go Client Git repo, add atomic changes with good commit messages. Keep white-space changes and technical changes fully separate (ideally: technical changes first, white-space changes last).
