I'm not that sure. The output could be changed to, for example
  <hash> SP <quoted-filename> [SP <quoted-filename> ...]
although I'm not sure if git can detect that two files were joined into=
 one
(or, in reverse that one file was split into several; this doesn't matt=
er
for following history of a file from top)

But --follow=3D<filename> with <pathspec> can be useful, e.g. when <pat=
hspec>=20
is a directory (or, perhaps in the future, glob), which would mean "fol=
low
the contents indicated in starting hash by <filename>, and stop followi=
ng
when it falls out outside given <pathspec>, in our case given directory=
".

As pathspecs doesn't change, there is no need to output them.
