[MonoDevelop] SourceEditorDisplayBinding.patch

[Jeffrey Stedfast]

I've been running into a few bugs while using it, unfortunately...

For example, if I create a new file and then paste a block of code into
it, hitting any arrow key will cause a crash (see attachment for
backtrace).

Also, in some cases, holding down an arrow key will lock the UI
indefinitely until I release the key. For example, try placing your
cursor at the top of a source file in the "using ...;" statements and
then press-and-hold the down-arrow key... the cursor may take a step or
two downward, but after that it will freeze until you release the key.

Once you are inside the namespaced region, though, I don't have this
problem... *until* I reach the end of the file, next-to-last closing
curly brace, then it happens again:


..
            some_code ();
        }
    } <-- cursor freezes as it tries to pass this brace (end of class)
}
