bug#3138: 23.0.92; doc of ediff-patch-file

[Drew Adams]

C-h f ediff-patch-file -> 
 
 (ediff-patch-file &optional ARG PATCH-BUF)
 

 Run Ediff by patching SOURCE-FILENAME.
 If optional PATCH-BUF is given, use the patch in that buffer
 and don't ask the user.
 If prefix argument, then: if even argument, assume that the patch is in a
 buffer. If odd -- assume it is in a file.
 

So what is SOURCE-FILENAME?
