Currently when I'm done fixing up a package and I've tested my changes locally I do:
fedpkg clog && fed commit -p -F clog && rm clog
It could be nice if I could just write:
fedpkg commit -p -z
That's pretty reasonable. Not sure I like "-z" but I get what you're saying. I have to poke at clog soon anyway to get rid of the first line it is using since that is redundant info for the most part, I could work on this at the same time.
"fedpkg commit -c" does this and has been around for ages
