Re: shell-expand-line drops quotation marks

[Keith Thompson]

And today I learned that there's an "undo" command!  (It's bound to

Ctrl-X Ctrl-U and to Ctrl-_ by default.)  Thanks, that's incredibly useful.

I still can't think of a case where I'd want quote removal, which changes

the meaning of the line, but I don't have to use it.

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.
