richedit: Fixed check for nOffset at the end of the cursor's run.

[Dylan Smith]

For some reason the code previously mixed up a selection cursor with the
result cursor.  The problem seemed to have corrected itself before as a
result of conversion between offsets and cursors, but my recent changes
made this bug more severe.
