[minor] display bug with comments, syntax highlighting and set to not "show all lines"

(sorry wrong repo - but I can't move it, nor delete it...)

Hi, first of all thanks for the tremendous work on this nice git SCM tool!

While happily using SourceGit mainly on macOS to do SCM I found that when

• there are multiple edits shown in the source diff window,
• the source diff windows is not set to "show all lines",
• syntax highlighting is enabled,
• the upper edit contains a starting comment (i.e. /* for C++) and
• the closing comment (i.e. */ for C++) is hidden between visible edits
  then syntax highlighting starts commenting, ignores the belonging but hidden closing comment and continues to commenting until another, unrelated, but in an edit visible closing comment is found.

Thanks and all the best!

This is a known issue and is generally difficult to resolve. Because TextDiffView displays the output of the git diff command instead of reading the files of the two versions separately and comparing them on its own. Meanwhile, syntax highlighting is automatically read and analyzed by TextMateSharp from the bound AvaloniaEdit component.
