I'm sure somebody thought that it would be a good idea to print that
warning, I can't imagine any reason that wouldn't outweigh its downsides
now though.  Do you have a link to the corresponding implementation
discussion?  Thanks.

I'm replying to that one separately.

This one contains merge conflict markers, so cannot have been tested
in this spelling.  The tests in this one assume that unset works (I'm
not judging that, just stating that it's the case).

If you (still) need somebody to test IRIX, OSF, Solaris 2.6, AIX, please
ping me.  I definitely would feel a bit less worried if these changes
were thoroughly tested before the next release.

Thanks,
Ralf
