Thanks everybody!  That ".." simply stands for "parent directory" seems
correct, as "meson setup" has positional arguments:

meson setup --help
[...]
positional arguments:
  builddir
  sourcedir
[...]

The "builddir" probably doesn't have to be specified if it's the working
directory ("build" in our case).

Nevertheless: I just built xorg-server and NetworkManager, each with
both above mentioned forms and from freshly unpacked sources and a
DESTDIR-installation.  And there were no problems.  All four builds
succeeded as usual and the test-results were identical.  Just to be sure
about the positional arguments, I also built xorg-server with

meson setup $(pwd) ..   \

and that also worked. ;)

Alright, case settled and closed, I think.  Thanks again for your input!

Rainer
