I now know again…

That's worse: Now the prompt _always_ shows
"/home/abe/.zsh/zsh.d/15-prompt" (which is the sourced file where the
PS1 assigning happens) instead of e.g. "/usr/bin/zsh". So that needs
some more fine-tuning.

$ZSH_NAME seems close, except that it doesn't show "su" if the shell
was spawned by using "su" (neglectable) and that it doesn't show the
leading dash if it's a login shell.

What I was looking for seems to be $ZSH_ARGZERO. So far that works
fine. I hope, it's backwards compatible to at least 4.3.9 from Debian
7 Wheezy. :-)

		Kind regards, Axel
