func Unquote

func Unquote(s string) (t string, err error)

Unquote interprets s as a single-quoted, double-quoted, or backquoted Prometheus query language string literal, returning the string value that s quotes.

NOTE: This function as well as the necessary helper functions below (unquoteChar, contains, unhex) and associated tests have been adapted from the corresponding functions in the "strconv" package of the Go standard library to work for Prometheus-style strings. Go's special-casing for single quotes was removed and single quoted strings are now treated the same as double quoted ones.
