Sure, when you want to expand aliases or variables in the command before
executing it.  It's only the quote removal that you -- in this case --
don't want.  You can also undo the word expansions after viewing them,
restoring the quoted strings.

There are separate bindable commands for history expansion, alias
expansion, and history-and-alias expansion.  If you don't want the
rest of the word expansions, you can easily rebind the commands.
