bug#114: Shell-mode: File completion breaks editing previous commands

[Glenn Morris]

For anyone like me who had trouble following the recipe:

emacs -Q -f shell
touch foo bar RET
echo foo RET
C-u 2 C-p
C-u 5 C-f
 ; point now on "f" of "echo foo"
baTAB
 ; completes so that line reads "echo bar foo", with cursor on "f".
RET
 ; -> tries to run the command "foo"


If you type "bar " by hand rather than using tab completion, there is no
problem.
