bug#18976: 25.0.50; packages with elisp in subdirectories

[Tom Tromey]

I'd like to distribute a package that has elisp in a subdirectory of its
top-level directory.  This works reasonably well because
byte-recompile-directory searches subdirectories.

However, autoload cookies aren't extracted from subdirectories, because
update-directory-autoloads doesn't do this same subdir search.

I'd like it if either update-directory-autoloads searched subdirs, or if
package.el did this.
