[Bug-AUCTeX] TeX-command-master fails if fun 'file' is defined.

[Bjørn Haagensen]

Hi,

If a function 'file' is defined running 'TeX-command-master' fails
with the following backtrace:

Debugger entered--Lisp error: (wrong-number-of-arguments (lambda nil
(interactive)) 2)
  file(t t)
  apply(file (t t))
  TeX-command-expand("%l \"%(mode)\\input{%t}\"" TeX-master-file)
  TeX-command("LaTeX" TeX-master-file nil)
  TeX-command-master(nil)
  call-interactively(TeX-command-master)

To reproduce use '(defun file () (interactive))'. Function 'file' does
not seem to be defined by auctex, so I think that if 'file' is used
internaly, auctex should not pick up global definitions.

My sys info:
Ubuntu Gutsy 7.10 (beta)
GNU Emacs 23.0.0.1 (i486-pc-linux-gnu, GTK+ Version 2.12.0) of
2007-10-01 on samarium
Auctex 11.83.

PS! I ran into this bug while trying out icicles for emacs. It seems
that the developer of icicles has seen this before, and in fact a user
has reported the following to him.
