-Permanently hide packages that match a regexp

+Hide packages whose names match a regexp
+(@code{package-menu-hide-package}).  This prompts for a regexp, and
+then hides the packages with matching names.  The default value of the
+regexp will hide only the package whose name is at point, so just
+pressing @key{RET} to the prompt will hide the current package.
