Well, there are different things.
To draw a glissando-line you need to tell LilyPond were to start and
where to end, this can't be unspecified.
The performer of said glissando may be told to do a glissando to an
unspecified pitch if no pitch is visible.

There are already possibilities to tweak appearance or even to skip a
note-column or rest

\version "2.19.82"

{
e'2\glissando e''
\once \override Glissando.bound-details.right.padding = -10
e'2\glissando e''
e'2\glissando
\override NoteColumn.glissando-skip = ##t
r
r
\revert NoteColumn.glissando-skip
e''
}
