I'm using nvim and LaTeX together, and for the most part it's been great. However, nvim appears to be incorrectly highlighting underscores that appear in filenames I include as part of the subfiles package (https://www.sharelatex.com/learn/Multi-file_LaTeX_projects#The_subfiles_package). At first I thought this was syntastic's fault, but I've verified that disabling syntastic does not solve the issue.
Here's what the highlights look like:
I think vim thinks that the underscores are an illegal character in this context, however the report compiles just fine.
Any suggestions on turning this behavior off? Maybe just in this context if possible?
