  ==============
ls -l /usr/local/libexec/*
ls: /usr/local/libexec/*: No such file or directory

How does an alias help ?
I see how a wrapper could 'pretend' to do it:
 before you exit to the wrapper, it could save PWD to a file [which is 'global'
and independent of any process]. And then the wrapper could set PWD.
I don't like the extra complexity of having to know if/what wrapper I'm in.
One good thing of school-teacher-style Debian is that some of the more complex
manS are easier to understand. So I've finally worked out how to make
"macro-keys",
which are also global. So my bash-based-micro-mc can save PWD to a
file, and after
it exits I'll just press eg. <F12> which will key:  cd `cat <file
which saved PWD>'.

No, I've installed those since 1995.
Each with it's own binary.

Yes, each mc installed automatically from the installation CD/fd0,
to its own partition, with its own /lib, without any problem.
What made me immediately feel strange/negative towards Debian, is
that it didn't install mc & gpm by default.
And uses the CD-space for other strange-stuff.
