// QuoteMeta returns a string that quotes all regular expression metacharacters

// the literal text.  For example, QuoteMeta(`[foo]`) returns `\[foo\]`.
QuoteMeta returns a string that quotes all regular expression metacharacters inside the argument text ; the returned string is a regular expression matching the literal text . For example QuoteMeta ( [ foo ] ) returns \ [ foo \ ] .
