eshell !foo expansion

[Christopher Howard]

Hi, I've been combing through the Emacs 30 Eshell manual, as I find the time. I 
like the !foo expansion syntax, which is very handy. However, I was wondering 
if there could be some function and keystroke added to expand the token 
immediately, so you could see the expansion before actually submitting the 
entire line to eshell. You might want to do this if, say, you weren't 100% sure 
that you are really calling up the desired history command, or perhaps you just 
want to make a slight tweak to the recalled command before running it.

The natural keystroke would be TAB, but that would conflict with preview 
complete, which is happening at the same time, so I'm not sure what would be 
best. Maybe just an interactive function would be enough.
