Unclear how I missed the May 5, 2018 response.
Deep apologies.

Finally done the removal of the bogus \{ sequence.

Looked over things a few times and I am wholly unclear why it was written with it. My best guess this late is that it was an accidental insertion I then missed, and then not thought about on the first "fix" (See [aec286d43d]).

Done with with commit [a136e80afe].

Version bump to 1.0.3.

Thank you for your patience here.
Hopefully this now truly done.
