html: UnescapeString documentation error

[icza]

Go 1.6, Go Playground environment

Documentation of html.UnescapeString() contains a mistake. Quoting:

It unescapes a larger range of entities than EscapeString escapes. For example, "á" unescapes to "á", as does "á" and "&xE1;".

It should be á (there is a missing hashmark # in the doc).

The implementation is good, but it is documented falsely.

fmt.Println(html.UnescapeString(`&xE1;`))  // Output: &xE1;
fmt.Println(html.UnescapeString(`á`)) // Output: á

Output is as expected.
