I was researching the history of some Emacs documentation
files. I got back as far as
http://git.savannah.gnu.org/cgit/emacs.git/log/doc/emacs/emacs.texi?ofs=200
which ends with the entry
2007-09-06 Move here from ../../man
which is
http://git.savannah.gnu.org/cgit/emacs.git/commit/doc/emacs/emacs.texi?id=8cf51b2c2f18417403f27fdc215f369af887d89b
How would I go back further in time than this to find the
previous revision of the file? I'm sure that revisions earlier
than September 2007 are recorded. Doesn't git have some way of
deducing when a file has been renamed?
