#2994 Crash after deleting text

GUI (476)

I had a file-comparison open and deleted all text on both sides (Ctrl-A, Del). Then I switched to another application, copied some text and wanted to copy it into one pane. But when switching back to WinMerge it crashed.
(may be related to Bug-ID: 3058807 - Crash on marking text)

The crash happened in the function GetLineFlags() when OnDraw tried to access lines that do not exist anymore.

    Thanks for the patch! This fixes the crash (and can be applied as such) but I think the real problem is why we try to get line colors for non-existing line...
