bug#11158: 24.0.93; ls #<TAB> signals the error "Wrong type arguemnt: wholenump, -1"

[Kenichi Handa]

This is with the latest trunk Emacs.

In *shell* buffer, when I type this (<TAB> means the TAB key):
   % ls #<TAB>
the error "Wrong type arguemnt: wholenump, -1" is signaled.

With toggle-debug-on-error, the *Backtrace* is as below:

Debugger entered--Lisp error: (wrong-type-argument wholenump -1)
  compare-strings(#("#" 0 1 (fontified t)) -1 1 #("\\#" 1 2 (fontified t)) nil 
nil)
  comint--common-quoted-suffix(#("#" 0 1 (fontified t)) #("#" 0 1 (fontified 
t)))
