fixes #251
wouldn't it make sense if you include a test case for such a subtle bug/edge case?
a contributing doc to explain how to add tests would have been nice instead of me having to reverse engineer this repo luckily https://github.com/microsoft/vscode-textmate/commit/7640bd6490ad961437a6982d7489e212777df7d8 is a clean commit to copy
@alexdima would you mind having a look thanks
this replaces the bad fix 7640bd6 for https://github.com/microsoft/vscode-textmate/issues/66
@alexdima @lszomoru @joaomoreno I noticed you were able to create and merge your own PR within a few hours. It would be greatly appreciated if you could also take a look at this community-provided PR, which has been waiting for review for over 6 months. It addresses an existing bug and deserves attention so it doesn’t get lost.
