it uses test "x$VAR" = x
Thus the manual should use the term "is nonempty", not "is set".
(One of the reasons for this behaviour is that unset is not portable.)
Another problem of the documentation is that the same pattern is repeated
in the description of each of the macros. I tried to fix this some time
ago, but then I put it ad acta with a note "this patch has to be repaired".
I attach the old patch, for reference. If you or anyone else here could
finish it, I'd be grateful.
Have a nice day,
