How to fmt.Printf an integer with thousands comma
formatting, go, printf, string
Solution
None of the fmt print verbs support thousands separators.
Problem
Does Go's `fmt.Printf` support outputting a number with the thousands comma? `fmt.Printf("%d", 1000)` outputs `1000`, what format can I specify to output `1,000` instead? The docs don't seem to mention commas, and I couldn't immediately see anything in the source.
