Lorep ipsum dolor sit amet, consectetur adipiscing elit. Donec euismod, nisi vel consectetur interdum, nisi nisi consectetur nisl, eget consectetur nisl nisi vel nisi.
#### <fantomas-setting-icon type="orange"></fantomas-setting-icon>indent_size
` indent_size` has to be between 1 and 10.

This preference sets the indentation
The common values are 2 and 4. 
The same indentation is ensured to be consistent in a source file.  
Default = 4.

Problem description

In fsdocs you can write markdown inside block comments.
Markdown will insert a <br /> tag when you have two or more trailing whitespaces.

Fantomas currently strips these whitespaces after formatting.
Hard to see in this example but The common values are 2 and 4. had two spaces after it in the source, but does not in the formatted result.

Extra information

• The formatted result breaks my code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}

@alanlomeli I believe the trimming in

fantomas/src/Fantomas.Core/Context.fs

Line 106 in a5c533a

| h :: tail -> String.empty :: (h.TrimEnd()) :: tail

should be removed here. Could you investigate this a bit? You can add a unit test to CommentTests.fs.
