That affects 'stg show' but not 'stg mail'.


It looks like 'stg mail' is generating the stats with git-apply on the results
of a diff:

	def diffstat(files = None, rev1 = 'HEAD', rev2 = None):
	    """Return the diffstat between rev1 and rev2."""
	    return GRun('apply', '--stat', '--summary'
			).raw_input(diff(files, rev1, rev2)).raw_output()

which seems to mean that I can't reduce them from the:

 arch/frv/include/asm/Kbuild              |    5

to the:

 {include/asm-frv => arch/frv/include/asm}/Kbuild   |    0
 {include/asm-frv => arch/frv/include/asm}/atomic.h |    0
 {include/asm-frv => arch/frv/include/asm}/auxvec.h |    0

 {include/asm-frv => arch/frv/include/asm}/bitops.h |    0
 {include/asm-frv => arch/frv/include/asm}/bug.h    |    0

though it is using git-diff-tree to generate the rest of the patch, which I
can affect with the diff options, it would appear.

Is there a way to get git-diff to produce just the stats and summary and not
the body of the patch?
