this fixes a panic which occurs when highlighting a JSON file using a recent version of
JSON.sublime-syntax
from the sublimehq/Packages repo. This bug was originally discovered at sharkdp/bat#644 - the steps for reproducing the panic are there.Note, I haven't added a unit test for this yet, and am not sure when I will get chance to work on one... If someone else wants to take it on, please do.
