AsciiExt::is_ascii_graphic documentation bug

[mateon1]

The documentation for https://doc.rust-lang.org/std/ascii/trait.AsciiExt.html#method.is_ascii_graphic is incorrect.

Checks if the value is an ASCII graphic character: U+0021 '@' ... U+007E '~'. For strings, true if all characters in the string are ASCII punctuation.

This seems like an accidental copy-paste error from https://doc.rust-lang.org/std/ascii/trait.AsciiExt.html#method.is_ascii_punctuation

Checks if the value is an ASCII punctuation character: U+0021 ... U+002F ! " # $ % & ' ( ) * + , - . / U+003A ... U+0040 : ; < = > ? @ U+005B ... U+0060 [ \\ ] ^ _ \ U+007B ... U+007E { | } ~` For strings, true if all characters in the string are ASCII punctuation.

Also, the ` quoting/escaping is inconsistent/broken for is_ascii_punctuation, and could be fixed, but that's a minor issue

The quoting issue seems to be fixed in the nightly version of the docs.
