Filename completion won't work at shell, when previously adirectory change using wildcards has taken place.

1) M-x shell
2) md -p foo1/dump; cd fo*;
3) Typing: 'ls du' and pressing Tab won't auto-complete 'dump'

Also, killing the shell with C-d and opening a new one at the same buffer
with M-x shell will place the new shell not in ~/foo1 but in ~ (I think
that this shouldn't be the case).
