bug#9554: 24.0.50; shell-mode completion broken

[Glenn Morris]

>>> 1) Create two files with `touch foo bar'. Then type `rm foo b' and try
>>>    to complete 'bar'.
>>
>> That was reported a few weeks ago by Kenichi Handa, and I happen to fix
>> it just a few minutes ago.
>>
>>> 2) Try to scp a local file (e.g. `scp /<TAB>'). pcomplete insists on
>>>    completing host names, not file names.

> 3) Open a buffer dedicated to a remote host, for example "C-x f
>    /scp:host:". Start `shell', it runs on the remote host. Goto a
>    directory which does exist on the remote host, but not on the local
>    one, for example "cd /sh <TAB>". It does not expand to "/share" as
>    expected, instead it tries to complete the filename on the local host.

Since it is better to have bug reports that focus on individual issues,
and since each issue in this report is the subject of another report, I
don't think this report needs to stay open. (The general issue of
"should shell use pcomplete by default" seems more like an emacs-devel
topic.)
