If you look at the << ... >> section, you'll see that you are here doing a 
quarter note in parallel with two quarter notes. In particular, the length of 
the << ... >> is two quarter notes, thus they remaining notes in the measure 
"appear" shifted due to that error. I suppose you rather want:
<< {e4 c} {s4\glissando s4} >> r8 e d c-.

Here the durations of the dotted half note and the three quarter notes 
concide...

However, I'm afraid that this issue does not solve you issue of note spacing. 
While I also don't have a solution for the spacing problem, you might change 
the padding for the glissando, so that it starts closer to the notes. This 
way, the zigzag is clearly identifiable:

\relative c'' {
  \override Glissando #'style = #'zigzag
  \override Glissando #'bound-details = #'((right (attach-dir . 0) (padding . 
1)) (left (attach-dir . 0) (padding . 1)))
  e4\glissando c r8 e d c-.
}

Cheers,
Reinhold
