I am not sure what "can't mark on an empty line" means.
Would you please state a precise test case so I can be sure
I understand?

Please read the Bugs section in the Emacs manual, which provides
guidelines on how to write a bug report to give us the
necessary information so we can fix the bug.

The following is from the discussion in the
gnu.emacs.help newsgroup:

With `transient-mark-mode' t the region becomes
inactive when you move to a buffer position that is
not yet created by `picture-mode'?

C-f/C-b/C-n/C-p should automatically insert spaces to
extend short lines when necessary. This does not
happen.

I hope the above description is clarifies the problem.
 

Sincerely,

Alas, it doesn't.  What I need is a precise test case telling me
exactly what to type so I can observe the problem.

Please read the Bugs section in the Emacs manual, which provides

necessary information so we can fix the bug.

Open a new buffer and type M-x picture-mode.

Press C-SPC to mark the current position.

Now, attempt to extend the marked region to the
rectangle size you desire with the following command:

C-f C-f C-f
C-n C-n C-n

This should've marked a region.  Now

C-c C-r should create a rectangle.

This _doesn't_ happen.  

Sincerely,

Emacs 21.2.1 doesn't have this problem.

But if you set `transient-mark-mode' to `t',
then Emacs 21.2.1 _does_ have this problem.

Yes, this patch fixes it!  Thanks a lot!  It wouldn't
apply cleanly to my version of picture.el (emacs
21.1), so I had to apply the changes by hand.
