Hi Max,

Not sure it will leave you feeling totally satisfied but the
following command will at least show you the copy which
occurred in that commit:

$ git log --full-diff -C --find-copies-harder --stat -- b.txt
commit 578ecbc516e70ce7178545233192a08369a07101
Author: xyz <x@y.z>
Date:   Tue Jan 29 13:11:16 2008 -0500

    Copy a.txt to b.txt

 a.txt => b.txt |    0 
 1 files changed, 0 insertions(+), 0 deletions(-)

If you had done a rename instead of a copy, then "git log --follow b.txt" would
have done what you're looking for, but there is no corresponding option to
follow copies.

HTH,
Sean
