`batch-byte-compile' for directories?

[Philipp Stephani <p.stephani2@gmail.com>]

Hi,

the function `batch-byte-compile' supports directories.  The code for
this is:

	  (let (source dest)
	    (dolist (file (directory-files (car command-line-args-left)))
	      (if (and (string-match emacs-lisp-file-regexp file)
		       (not (auto-save-file-name-p file))
		       (setq source
                             (expand-file-name file
                                               (car command-line-args-left)))
		       (setq dest (byte-compile-dest-file source))
		       (file-exists-p dest)
		       (file-newer-than-file-p source dest))
		  (if (null (batch-byte-compile-file source))
		      (setq error t)))))

What I find weird is the condition that the destination file has to
exist for the compilation to be performed.  I would expect logic similar
to the explicit file case (don't check destination file by default, and
if NOFORCE is set check for either nonexistent or old destination
file).  Is the current behavior intended?

Thanks,
Philipp
