Sorry for making a crusade out of this topic, but one more little piece of
data.

It looks like this works by writing the file ~/.emacs/eshell/alias

But in the file it is stored without the single quotation marks.

However, if you try to interactively define the alias without the single
quotation marks, it does not work.  Rather, what you get is two commands:
the alias, and then the ls.

So however eshell is reading the the alias file seems to not be the same as
the way it reads the command line.

Anyhow, i'll take my oar out of the water now, thanks again Stefan and
Christopher for the information.
