The culprit would seem to be this, starting at line 502 in the function LilyPond-blink-matching-paren in lilypond-indent.el:

  (when blink-matching-paren-distance
        (narrow-to-region
         (max (point-min) (- (point) blink-matching-paren-distance))
         (min (point-max) (+ (point) blink-matching-paren-distance))))

 

This narrowing is never undone.

Agreed, and the canonical way to solve this is by adding a "(save-restriction ..." block around this section.  Something like this (untested): 

  (when blink-matching-paren-distance
        (save-restriction (narrow-to-region
         (max (point-min) (- (point) blink-matching-paren-distance))
         (min (point-max) (+ (point) blink-matching-paren-distance)))))

 

 

One solution might be to simply comment out this code, but I don't know if that might have some undesirable side effects.

Another solution might be to put a (widen) just before the function returns.  I think a widen on an un-narrowed buffer has no effect.

I haven't tried either of these, so proceed at your own risk.
