Format python with black

[ralphbean]

Just for consistent style.

This includes changes from #279.

I'm a fan of using Black, even if I don't necessarily like everything that it does.

I've called out a few things below:

• Foremost, it looks like you included a commit on this branch which belongs in a separate PR.
• Beyond that, there are a couple of changes that Black made that I think you might want to resist in various ways.
• And, finally, the changes highlighted a couple of spots in the code where we might want to make some tweaks beyond what Black proposed...which you should feel free to decline.

[I don't know whether you're interested in making this sort of change, but I'll point it out and you can decline if you like....]

Since we're going to include x in the result if it is changed, we should check that before checking to see if the comment is in j_comments.

Using the ** operator on a literal is a little heavy-handed, we should do something like this, instead:

Suggested change

	return jira.client.JIRA(
	**{
	"options": {
	"server": URL,
	"verify": False,
	},
	"token_auth": TOKEN,
	}
	)
	return jira.client.JIRA(
	options={
	"server": URL,
	"verify": False,
	},
	token_auth=TOKEN,
	)

[Again, feel free to decline if you aren't interested in this kind of change in this PR.]
