[MonoDevelop] A question on dynamically change the SyntaxMode of Mono.TextEditor.Document

[Doug Blank]

Following up an old thread. In recent MonoDevelop, I can't get any
combination of calls to reformat on changing the mime type:

// FAIL: does nothing
texteditor.Document.MimeType = new_mime_type;
texteditor.Document.UpdateHighlighting();
texteditor.Document.CommitUpdateAll();
Mono.TextEditor.Highlighting.SyntaxModeService.WaitUpdate(texteditor.Document);

However, this works:

// HACK:
texteditor.Document.Text = texteditor.Document.Text;

I referenced Mono.TextEditor.dll from MD 2.2.2 release, and in this
version, SyntaxModeService.WaitUpdate doesn't exist.
However through viewvc I can see WaitUpdate in the trunk source, I'll
try it later when I have time to checkout and try the code. since
suddenly I just find that I don't really need to change the syntax
mode on the fly.
