Return a new string containing the replacements.
Optional arguments FIXEDCASE, LITERAL and SUBEXP are like the

REP is either a string used as the NEWTEXT arg of `replace-match' or a
function. If it is a function it is applied to each match to generate
the replacement passed to `replace-match'; the match-data at this
point are such that match 0 is the function's argument.
