bug#16942: 24.3; replace-match does not return t as stated in the manual

[phillip.lord@newcastle.ac.uk (Phillip Lord)]

This is a small documentation bug.

From info node: `(elisp) Replacing Match' 


     If you did the last search in a buffer, you should omit the STRING
     argument or specify `nil' for it, and make sure that the current
     buffer is the one in which you performed the last search.  Then
     this function edits the buffer, replacing the matched text with
     REPLACEMENT.  It leaves point at the end of the replacement text,
     and returns `t'.

    
In my hands, replace-match returns nil regardless. The docstring does
not mention the return type.
