+Summary: [X11] Releasing Alt after a mnemonic should generate WM_KEYUP
+If you press and release the Alt (Menu) key, it should produce a
+msg=0x104 (WM_SYSKEYDOWN) hwnd=0x3510dc wparam=0x12 lparam=0x20380001
+msg=0x105 (WM_SYSKEYUP) hwnd=0x3510dc wparam=0x12 lparam=0xc0380001 result=0x0
+However, if you press the Alt key, press another key (like F), and then
+release the Alt key, you should get a WM_KEYUP instead of a WM_SYSKEYUP for
+the Alt key:
+(Alt pressed)
+msg=0x104 (WM_SYSKEYDOWN) hwnd=0x3510dc wparam=0x46 lparam=0x20210001
+(F pressed)
+msg=0x106 (WM_SYSCHAR) hwnd=0x3510dc wparam=0x66 lparam=0x20210001 result=0x0
+(F released)
+msg=0x105 (WM_SYSKEYUP) hwnd=0x3510dc wparam=0x46 lparam=0xe0210001 result=0x0
+(Alt released)
+msg=0x101 (WM_KEYUP) hwnd=0x3510dc wparam=0x12 lparam=0xc0380001 result=0x0
+X11 currently sends a WM_SYSKEYUP instead of WM_KEYUP for the last case. 
+This is needed by Menus because Alt, F is handled differently that Alt+F.
+Form that prints out just these messages is attached.
