Cosmetic git-am interactive bug

Just now, I was exploring git-am's interactive mode, so as to comply 
with Linus's urgings of a cleaner changelog <grin>.  I had a raw email 
changelog with the subject

	Re: 2.6.24-rc3-git6: Reported regressions from 2.6.23

I used the [e]dit feature of interactive mode to change this 
first-line/one-line summary to

	pata_amd/pata_via: de-couple programming of PIO/MWDMA and UDMA
	timings

When I hit [y]es to apply the patch, git reported

	Applying 2.6.24-rc3-git6: Reported regressions from 2.6.23

	Wrote tree 34cebd48e3b4e90fe3e6a6c6c03154ae1ed0c827
	Committed: 943547abdfe9b4e27e36a25987909619908dffbf

The use of the older one-line summary led me to believe that it had not 
committed my changelog edits.  Looking at the result, however, proved 
that the commit changelog was my new, corrected version.

Thus, I concluded that the printing of the old-and-no-longer-valid 
changelog during the commit-to-tree phase was a bug.

Please see attached file for full example.

Thanks,
