@defun match-substitute-replacement replacement &optional fixedcase literal string subexp
This function returns the text that would be inserted into the buffer
by @code{replace-match}, but without modifying the buffer. It is
useful if you want to present the user with actual replacement result,
with constructs like @samp{\@var{n}} or @samp{\&} substituted with
matched groups. Arguments @var{replacement} and optional
@var{fixedcase}, @var{literal}, @var{string} and @var{subexp} have the
same meaning as for @code{replace-match}.
