Subject: [PATCH] std::fmt: Added argument index comments to examples for
 specifying precision

The examples for specifying the precision have comments explaining which
argument the specifier is referring to. However, for implicit positional
arguments, the examples simply talk about "next arg". To make it easier for
readers to follow the comments, "next arg" was supplemented with the actual
resulting argument index.
