Description
👋 from github-linguist/linguist, the library GitHub.com uses for language detection, and also the repo that tells our syntax highlighter which grammars to use.
The Lua grammar was recently switched to using this repo in github-linguist/linguist#6661 and our grammar compiler has found some malformed regexes in the Lua.plist file. These aren't found in the lua.tmLanguage.json so this is likely to be an inconsistency between the two files:

If it helps, our grammar highlighting engine uses PCRE for performance reasons.
