Don't we determine all the files that would be listed in the diff
anyway?  The diffcore pipeline collects all the different filepairs,
matches them up for rename/copy detection, and finally do the output
formatting for each individual filepair.

None of the above seems like a problem to me at least from the
presentation and consumption sides.  There is no rule that extended
diff headers has to fit on a 72-char line, cannot use line folding
by inserting LF-SP in the middle of a logical line, and there
already is at least one case we give an extended diff header without
a single line of content change (namely, "chmod +x README").

Thanks.
