LilyPond prints precisely as much music as you provide.  If you only 
input a few notes, then that is all you will (and should) get.

If you require additional empty space, simply use the spacer rest.  For 
instance, "s1*10" will result in the space equivalent to ten whole 
notes.

You can use simultaneous music to make this process very clear.  
Consider:

%%%%
  << \new Staff \repeat unfold 4 \relative c' { c4 d e f | g a b c }
     \new Staff << \relative c' { c8 d e f g } \\ { s1*8 } >> >>
%%%%

Here we have a second staff with only five quavers for the time being, 
and we would like the staff to extend as long as the eight measures 
above.  The << \\ >> construct makes it easy to independently specify 
the notes for display as well as the desired overall duration.
