bug#28568: 26.0.60; [eshell] Incompatible change in alias argument handling

[Jay Kamat]

Hi!

I was getting quite annoyed with this bug (since it breaks all my eshell
aliases), and I would really hate to see this bug in the emacs 26
release, so I wanted to push it along. I've attached a patch that simply
reverts the fix to #27954 (commit e66e81679c), which seems to solve the
problem.

>From bug #27954, the issue was:

which can be fixed by changing the alias to:

alias ll 'ls -l $*'

which works fine for me in both cases ('ll' and 'll test.txt').

All this patch is doing is reverting commit e66e81679c and updating the
alias documentation, so feel free to remake and commit this yourself if
you wish (or if I'm doing it wrong).

Thanks,
-Jay
