Yes and no. For the most part, these cover the basic formatting style used.
On the other hand, always respect the format that has already been
established, unless is ridiculously out of whack.

I think there are various approaches and everyone has a slightly different
preference. I like fewer patches, but that's general because I prefer very
targeted changes, which generally aren't large. For bugs, it's nice to have
a test patch that can be applied and show the failure, which is separate
from the fix patch.

Bugs - describe the bug, why it's a bug and how the bug is fixed
Enhancement - describe what it is, describe the value (don't assume it's

Personally, I don't think POC work should be put into JIRA, at least not in
general. This is just normal development and it should be brought up in the
mailing list. A POC, in essence is just an idea that's illustrated with
code. Ideas have to be discussed and communicated before they can make it
into the code base and the only place to do that is the mailing list.
