text in --stat is colored like color.diff.plain

I noticed, that the filenames and the text "X files changed, Y
insertions(+), Z deletions(-)" in the --stat output ended with an ESC[m,
although they were not colored. Further investigation showed, that
these parts of the output indeed can use colors from color.diff.plain.

Is this intention? Commit 785f743 (diff --stat: color output.,
2006-09-26) introduced it, but only mentioned colored output of the
+++++++---- diffstat graph in the commit message. color.diff.plain is
documented for coloring context text and I don't think it looks good
either as it is now, nor is this really "context text".
Note: --shortstat and --summary don't use colors like --stat. Or is this
really intention and I don't see the reason for it?

If not, should we remove the colors for --stat?
After that maybe we could do some more color.diff.old/new coloring for
"Y insertions(+)", "Z deletions(-)", "create mode ...", "delete mode ..."
