If a non-existing file is open as the 1st tab (opened then file is deleted outside of Notepad++), and "Close All BUT this" is run, then current document will be closed.
Fix#8617
The reason, why the flicker occurs, is the following: There are two Windows messages sent by Windows to Scintilla, when the mouse is moved: WM_MOUSEMOVE and WM_SETCURSOR.
WM_MOUSEMOVE informs Scintilla, that the mouse has been moved inside its window.
WM_SETCURSOR informs Scintilla, that the mouse cursor has been moved. Anywhere, not necessarily in its window.
Scintilla calls the Windows function SetCursor (, which sets the mouse cursor shape, not the position), while processing both messages. Unfortunately, Scintilla uses different ways to calculate the desired cursor shape. So, whenever the mouse cursor is moved, two SetCursor calls are applied, sometimes with two different cursor shapes.
On WM_MOUSEMOVE, Scintilla calls ButtonMoveWithModifiers, which sets the correct cursor shape.
On WM_SETCURSOR, Scintilla calls SetCursor directly, sometimes with the wrong cursor shape.
This PR shows how to eliminate this effect in the modified Scintilla version used by Notepad++. This may be the fastest way to get results without introducing new effects.
The current original Scintilla version (Version 4.4.4, downloaded 2020-07-30, 5d134721c303ceecbdcb28ec82b28f0cbbdb4a55) has the same effect and can be fixed in the same way, although the WM_SETCURSOR code has been changed a little. Before updating to a new Scintilla version, we should try to get it fixed in the original Scintilla.

Fix accented characters in ANSI files not found in "find in files" and "replace in files" commands issues.
This regression (in v7.7 from v7.6.6) is due to the upgrade of Scintilla from v3.56 to v4.14.
