Command Line Slideshow don't end after last file.

[bortao]

If I call irfanview with command line option /slideshow, for instance

i_view64.exe /slideshow="C:\images\photo.jpg"

, it display the last picture, then go to a blank window, show it for the set time, and only then exits.
It used to work correctly (quit immediately after last picture), but I recently upgraded from 4.60 to 4.66 and now it is working like this. So the bug must have been introduced in this time.

Here is the Slideshow section of my i_view64.ini
