I found when I was doing testing on my SCI_VETOMODIFICATION patch that the line copy clipboard format used by Microsoft Visual Studio has changed from "MSDEVLineSelect" to "VisualStudioEditorOperationsLineCutCopyClipboardTag". This means that line copy between Scintilla and Visual Studio 2010 doesn't work.
I'm not personally in the habit of using line copy (I didn't even know about it until I read the Scintilla source code), so I don't mind how this is resolved.

(Column select "MSDEVColumnSelect" is still fine.)
Since it is near feature freeze for Scintilla 3.4.5, I won't be looking at this now.
Committed fix as [85d972].
