-This function replaces the text in the buffer (or in @var{string}) that
-was matched by the last search.  It replaces that text with

-If you did the last search in a buffer, you should specify @code{nil}

+This function performs a replacement operation on a buffer or string.

+If you did the last search in a buffer, you should omit the

 If @var{fixedcase} is non-@code{nil}, then @code{replace-match} uses
 the replacement text without case conversion; otherwise, it converts
