Re: Is there a --stat or --numstat like option that'll allow me to have my cake and eat it too?

What I really want is something for git-log more like
git-for-each-ref, so I could emit the following info for each file
being modified delimited by some binary marker:

    - file name before
    - file name after
    - is rename?
    - is binary?
    - size in bytes before
    - size it bytes after
    - removed lines
    - added lines

I think no combination of git-log options or any built-in machinery
comes close to giving me all of that without having to do multiple
passes with some combination of git-log and git-show, but I'd love to
be proven wrong.

I do not think such a thing exists.  From the look of the above
list, if I were implementing it, I'd think it would be the easiest
if it is built as a new output format of "diff" that sits next to
existing --stat, --patch, and --numstat formats, i.e. you would be
writing a new aevars_stat_consume() callback function and calling
xdi_diff_outf() like everybody else.  A possible output format may
look as if we are showing "log --patch" output with a bit more
extended diff header lines (e.g. in addition to "rename from", etc.,
you would have "bytes before" and other new types of headers), but
without the actual patch text.
