Extension css for output

[w0rm]

I would rather pipe the result through gulp-rename for more explicit transformation.

According to gulp plugin guidelines

Your plugin should only do one thing, and do it well.

For example, renaming affects the source map too, if we missed this, it could have caused unexpected behavior. gulp-rename is battle tested and there is no need to replicate its functionality.

If you still find this confusing, a PR to update the readme with how to use gulp-postcss and gulp-rename together to support .pcss extension is welcome!

Thank you for the answer!

I didn't think it was done on purpose. Gulp plugins for nunjucks, pug, scss, less etc. change the extension ourselves. Especially considering that in gulp 4 automatic renaming works fine (if I get right), for example in gulp-postcss this is done by adding file.extname = '.css' on line 50.

So yes, still find this confusing. Updating the readme to make it clearer.
