Add linebreaks before perl blocks.

Considering the difficulty we've had I used a script to identify likely
places where perl-quoted blocks did not follow an empty line.  These two
places were identified.  Only one of them appears to be rendering
incorrectly live, which simply adds to my confusion.

Regardless, I tried some additional checks for txt/shell/bash blocks and
did not find any others.  This does not mean that they do not exist.
