darcs changes offline-safe

will do this.  (Or for that matter, `darcs changes Easter Bunny`, or
`darcs changes -s`.)

Pull is never lazy about retrieving data, so any single command that
requires that darcs examine all the patches in the repository will make
that repository permanently unlazy (unless perhaps the --ephemeral option
is used).  Although, of course, you could always make it lazy again by
using rm _darcs/patches/*.  Or extra-lazy by also doing rm
