Subject: [PATCH] TLS uses an empty quoted string for these

Unfortunately, this pushes our line length up by one.  Rather than
reformat, I've tweaked the linter.  I'm not seeing that fail and it
still allows a 3 character gutter on both sides of diagrams in the
72-column text format, but I'd appreciate it if this could be
sanity-checked.

Closes #4503.
