command-line-args

[Katsumi Yamaoka <yamaoka@xxxxxxx>]

Hi,

There's a strange behavior that the recent Emacs calls a
FUNCTION interactively when the command line arguments

-f FUNCTION

are given.  How to reproduce it is:

Fill the ~/.emacs file only with the following function:

(defun testing (&optional str)
  (interactive (list (read-string "What? ")))
  (insert (format "%s\n%s\n"
		  str
		  (prog1
		      command-line-args-left
		    (setq command-line-args-left nil)))))

Type the following command in the terminal emulator:

emacs -f testing foo bar baz

Emacs 21.3 does only insertion of text in the *scratch* buffer,
but 21.3.50 prompts user for a string.  Is it a bug or a feature?
Because of this behavior, I can't use the following:

emacs -f w3m http://some.news.site/daily-news.html&;

Where w3m is yet another web browser command which has the
interactive spec for prompting a url.

Regards,
