Problem with LESS &:extend()

[mandulaj]

Hi, I found a problem when beautifying LESS files
When I have something like this:

.some_class {
   &:extend(.some_other_class);
  //... some more code
}

atom-beautify adds a space between the &: and the extend so the result looks like this:

.some_class {
   &: extend(.some_other_class);
  //... some more code
}

The resulting code does not compile 😞
This does not happen for &:hover
My best guess is that the extend keyword is not on some list of verbs whereas hover is. I set atom to beautify my code on save, now I had to disable it because of this problem.
Thank you in advance!

I've seen similar problems before, you are definitely on the right track with extend keyword not being on the list.

LESS uses the same beautifier as SASS:
https://github.com/Glavin001/atom-beautify/blob/master/lib/language-options.coffee#L190-L192

They use prettydiff:

Here's Prettydiff:

And looks like there is a closed issue!
prettydiff/prettydiff#31

I'll give it shot sometime this weekend and test your sample code. Hopefully this can be resolved quickly. Thanks!
