bug#10457: (Broken?) programmable completion in shell buffers |

In `pcomplete/tar', the call to `pcomplete-opt' happens inside a
(while (pcomplete-match "^-" 0) ...) loop. Here is a minimal example
that has the same problem as `pcomplete/tar':
(defun pcomplete/shell-mode/foo ()
(while (pcomplete-match "^-" 0)
(pcomplete-opt "hv")))
Start emacs with -Q flag, evaluate the above code in the *scratch*
buffer, start a shell, type "foo -", hit TAB. A completions buffer
showing two completions "-h" and "-v" should pop up. Press SPC --
voila, Emacs is locked.
