[PATCH] diff --stat: do not do its own three-dashes.

[PATCH] diff --stat: do not do its own three-dashes.

[Junio C Hamano]

I missed that "git-diff-* --stat" spits out three-dash separator
on its own without being asked.  Remove it.

When we output commit log followed by diff, perhaps --patch-with-stat,
for downstream consumer, we _would_ want the three-dash between
the message and the diff material, but that logic belongs to the
caller, not diff generator.

 * Now the next task is to make "git log" not to do its own
   commit formatting, but let the log_tree_commit() do it, just
   like we do in diff-tree --pretty.  This would open the door
   for us to (optionally) omit log message when there is no
   diff, and honor the --max-count by counting what we actually
   output.

   When that happens, the printf() I moved tentatively to
   cmd_log() should become part of the commit formatting
   log_tree_commit() does, perhaps with --pretty=format-patch.
