This is actually the most important patch, because it unveils many
typos/thikos in specfiles, and it can be instrumental in improving
package base (as opposed to improving rpm code base proper, with no
overt impact on the packages).
Since Fedora 19 is in its early stage of development, and since RHEL7
probably won't be using rpm-4.11+ anyway, I wonder whether this is the
right time and otherwise a good idea to make a release with this patch
applied (along with a few other patches related to syntax). If it turns
out to be a good idea, I'm willing to spend more time and come up with
"full coverage" results for Fedora 18 specfiles (I have already posted a
rather detailed if preliminary analysis of some common errors).
