CSharpier keeps adding a newline every time a file is formatted

[bvanreeven]

Input:

Given the following, already correctly formatted, C# file:

using System;

namespace MyCompany.MyNamespace;

// Comment block

Running CSharpier (v0.30.3) on the file (with the --no-cache flag) will add a newline between the namespace and the comment block every time the file is formatted.

Also, running CSharpier with the --check flag will mark the file as having a formatting issue.

Output:

• A newline is added to the file every time it is formatted.

Expected behavior:

• The file remains formatted the same way, even when running CSharpier multiple times.

I remember taking a look at this awhile back after running into it somehow and thinking "this won't ever come up in the real world" when I couldn't find an obvious fix. I'll take another look at it

@belav Thanks for fixing this issue!

This was a real-world case where we commented out a whole file (except for the namespace part) as part of a refactoring, and then forgot to remove the file. So, as a workaround, we were able to just remove the file. But I thought it would be good to report the issue just to prevent anyone else from running into it.
