[Qemu-devel] [PATCH v2 6/7] qemu-img: clean up dd documentation

[Reda Sallahi <fullmanet@gmail.com>]

The dd section on qemu-img --help was a bit hard to read since it was not
well aligned. This patch fixes the display problem and also makes the
sentences on the .texi file more consistent with one another (uppercase and
conjugasion).
