Thanks for tracing it back further.

My current theory is that it was done to regularize the device slot on
Windows and non-Windows, where Allegro's default is different (nil on
Windows and :unspecific on non-Windows).  Unfortunately, the reason
for this difference is lost in time (oh, the 90's).

If I find I have time, I may do tests you suggest.  Thanks.
