bug#19031: 24.4; find-file in icomplete-mode shows completions with no input

[Ole Laursen <olau@iola.dk>]

Run emacs -Q, evaluate

  (icomplete-mode 1)

then press C-x C-f and wait a second. There's now completions in the
minibuffer despite icomplete-show-matches-on-no-input being nil. Perhaps
icomplete is confused by the current working dir being present in C-x
C-f.
