Vi ---> Substitute replacement patterns

The basic meta-characters for the replacement pattern are "&" and "~"; these are given as \& and \~ when nomagic is set. Each instance of "&" is replaced by the characters which the regular expression matched. The meta-character "~" stands, in the replacement pattern, for the defining text of the previous replacement pattern. Other meta-sequences possible in the replacement pattern are always introduced by the escaping character "\". The sequence \n (where n is an integer between 1 and 9) is replaced by the text matched by the nth regular subexpression enclosed between \( and \). The sequences \u and \l cause the immediately following character in the replacement to be converted to uppercase or lowercase respectively if this character is a letter. The sequences \U and \L turn such conversion on, either until \E or \e is encountered, or until the end of the replacement pattern.
