bug#9161: 24.0.50; incorrect completion-at-point in *shell* buffer

[Kenichi Handa]

With the latest trunk Emacs, the command completion-at-point
(TAB) in *shell* buffer yields wrong completion.

Provided that you have a single directory '0 a'.
% ls 0<TAB>
is completed to
% ls 0\ a

But,
% cd 0<TAB>
is completed to
% cd 0 a

Note that the space between '0' and 'a' is not escaped by '\'.
