23.0.93; tab completion flakey with tramp when insert-default-directory is nil |

With the following in my .emacs:
(setq insert-default-directory nil)
tab completion when using tramp to access a remote file becomes flakey.
It seems that the notion of the current working directory becomes lost,
so tab completion ends up with doubled up directories, eg:
/home/chris/afolder/afolder
...where afolder doesn't exist, resulting in errors such as the following:
File error: tramp-handle-file-name-all-completions: Couldn't `cd
/home/chris/afolder/afolder/'
This doesn't happen right away, but I usually end up bumping into it
when navigating
around a folder structure by inserting .. a number of times in the
minibuffer window.

where you see that default-directory moves up one level each time the
*Completions* buffer is refreshed.
The patch below fixes the problem,
