extends support "," syntax.

[jqhr]

The extends could support multiple filetypes?
For example

extends html,javascript,css

I have tried this, but not work.
The code must be

extends html
extends javascript
extends css

For honza/vim-snippets, it's vue snippets has support above syntax.
Could support this feature?

Yes, that syntax should be supported. I opened a issue.
