GNU Emacs 18.55.1 of Tue Oct 31 1989 on marat (hpux)

Current GNU Emacs does not have a "create directory" function.  This
would be especially useful when one's reorganizing one's files and
thus creating new directory structure.

The simplest and most intuitive interface I can think of would create
directories as necessary for write and rename operations.  It should
presumably not do this without asking.

From a reprogramming point of view, it might be easiest to put this in
read-file-name and expand-file-name.  That is, if you tried to do
completion on a non-existent directory, it would ask you: "Create
directory foo/bar/q (y or n)?".

Are there any cases where (interactive "F") or read-file-name does not
expect to create the new file if it does not exist?
