t4008: correct stale comments

A complete rewrite of a single file was originally designed to be
expressed as a deletion immediately followed by a creation of the
same file, and the comments in the test updated here were written to
reflect that design decision made in f345b0a0 (Add -B flag to diff-*
brothers., 2005-05-30).  However, we later realized that a complete
rewrite is merely how a textual diff should be represented at
366175ef (Rework -B output., 2005-06-19), and updated the actual
tests.  But we forgot to update the introductory text while doing
so.
