splash-screen and visiting file with command arg => help menu broken

[Philippe Waroquiers]

do the following:
  touch bidule.el
  emacs --no-init-file --no-site-file ./bidule.el
  while the splash screen is there, click mouse-left (to see the file)
  click on  Help -> Search Documentation -> Find Command by Name ...
   this click has no effect.

It looks like there is one way or another a strange interaction between
the splash screen, the emacs lisp mode, the click and the Help menu.

Note that when I use bidule.txt instead of bidule.el, it works.
If I do not give a filename arg, and just clicks in the splash screen,
then it works

Note that the same actions do not cause a problem on an emacs 22
compiled on gnu/linux (Red Hat Enterprise Linux AS release 3 (Taroon Update 4))
with X toolkit, while this emacs 22 (on hp-ux) has been compiled with Motif.
