The \after command solves this problem: say you have this music:
{ c'2. c'4 }
...and you want to add markup text to the second beat. There is no note on
the second beat, so you would write:
{ \after 4 ^\markup "A" c'2. c'4 }
That is, after a duration of 4, add ^\markup "A" as if a note were there.
Now in the case of the glissando, you really don't need \after, you could
just write:
\relative c'' {
\time 3/4
\override Glissando.style = #'zigzag
c4 c4
c4*7/8\glissando
\hideNotes c,,32 \unHideNotes
\bar "|"
R2.
}
