In Npp 4.8.2 (SVN rev. 145) there is still a bug concerning wrapping.
When wrapping is disabled (after having enabled wrapping) and there are wrapped lines above the first line of the view, the view is moved down several lines.
DisableWrappingViewMoveFix_Patch.patch fixes this bug: The view position is saved before in IDM_VIEW_WRAP and restored afterwards in SCN_PAINTED, as Scintilla doc. says.
