language/printer not handle line break for comment inside args

[johannpinson]

Hi guys,

I report you a bug find with the graph.cool team and about Prisma cli and the generation of the SDL schema.
You can see the initial discussion here: https://github.com/graphcool/prisma/issues/2047

The bug is about highlighting in VSC (maybe a bug about the GraphQL Syntax plugin), but in fact I see a difference between the function printSchema and print.
The problem is just about a missing line break before a comment when it's about args for a "function"

If printSchema was fixed previous month (here #1205), the print function not handle correctly comments for function's args:

graphql-js/src/language/printer.js

Lines 131 to 138 in 3493edd

	FieldDefinition: addDescription(
	({ name, arguments: args, type, directives }) =>
	name +
	wrap('(', join(args, ', '), ')') +
	': ' +
	type +
	wrap(' ', join(directives, ' ')),
	),

I think it just need so verification so see if the args begins or contains some comments to add a line break.

Thanks for your help!

Thanks for the report. This is definitely a bug in VCS's syntax highlighter, however I agree that the output of print() could be improved
