Pull in documentation/whitespace fixes and improvements from the HEAD

revision of src/usr.sbin/pkg_install as of 20050204.  I ran:

	cd pkgsrc/pkg_install/files
	./pkg_install2nbcompat .

Then I ran "cvs diff" and looked for portability-related changes that
were removed as a result of the import and resurrected them from the
repository.
