Seems like a valid bug to me. Any reason this needs to be 'NeedsDecision' ?

@agnivade No reason other than me misunderstanding the labels, it seems.

The related code is in package go/printer:

• printer.exprList checks whether the arguments are on a single line (line == endLine).
• If the arguments span multiple lines, the comma is inserted correctly.
• If the code for the single-line case is deleted, the comma is inserted correctly, but the comment is not indented properly.

Test cases:

package main

func issue27574a() {
	print("",
		/**/)
}

func issue27574b() {
	print(`
	`,
		/**/)
}

func issue27574c() {
	print(
		"",
		/**/)
}

func issue27574d() {
	print(
		"",
		/**/)
}

func issue27574e() {
	print("", "",
		/**/)
}

Too late for 1.12
