In renaming a widget, pending text is commit when a nautilus toplevel
window gets focus-out,
but in CJK locales, it is not working well, since the input methods need to
bring up toplevel 
windows called "lookup-choice-window"  during text-input operation.

To fix this, I want to propose a change not to end renaming mode at
focus-out, but this will 
make nautilus crash when closing the nautilus window while renaming
operation is not 
completed, so this should be also avoided somehow if the change for
focus-out can be made.

Attaching a working-in-progress patch, which is likely said to be incorrect
or unacceptable, 
though...
