Description:
This is a simple revert of the problematic lines in the original commit
- I've not done any study as to why these are the problem, but this
change makes -dpreview function as it should once again when there are
braces and brackets present.  I've pixel-compared and the only change is
a very minor shift in the bar number on beam-broken-difficult.ly
