quoted strings, see [1].

Hi,
sorry, I did not see this earlier. Can you please go via the upstream
repository first? In this case this would be
https://github.com/vim-erlang/vim-erlang-runtime and you may want to
remind them to send updates back to Vim.

If you don't see any reaction there, I can go to include it here, but
I'd like to give the maintainers a chance to have a look at it.

Thanks,
Chris

Mit freundlichen Grüßen
Christian

Hi,

Indeed, sending a PR to https://github.com/vim-erlang/vim-erlang-runtime would be the best. It would be nice if you could also extend test/test_syntax.erl with the new language features.

Otherwise (if you don't have a GitHub account for example) I can create a commit based on your patch.

Regards,
Csaba

Good morning,

thank you for the info! I thought it's developed in here.
I have a GitHub account, but thank you for the kind offer :-) I will PR
it there.


Have a nice day!
Johannes
