"In my opinion":
Each variable has a default header. The default header
can be overridden by appending an equals sign and the
new text of the header. The rest of the characters in
the argument shall be used as the header text.
That is a quote from SUSv3. I believe 5.x presently tries
to follow that, and that is what I think it should do. As
to 4.x, the only reason 4.x still behaves the way it does is
that I avoided MFC-ing any commits which would *alter* the
behavior of how something worked in `ps'. The only things I
MFC-ed were commits that cleaned up the code, or which added
new features.
