bug#36103: 24.5; Blank spaces around parentheses in history expansion in shell mode

[Enric Rodríguez Carbonell]

Hi,

I would like to report what I think is a bug in the history expansion in 
shell mode.

This is the sequence of steps:

$ emacs -Q

Once in emacs:

M-x shell

Then I type in the command line of the shell window:

$ for file in $(ls); do echo $file; done

Then I type at the prompt:

$ !for

and then run command:

M-x comint-replace-by-expanded-history

which replaces the

$ !for

by

$ for file in $ ( ls ) ; do echo $file ; done

The blank spaces around the parentheses should not be there.
Because of these blank spaces, this command cannot be executed,
as "$ (" should be "$(".

Best regards,

Enric
