Stable Release Update wiki page update

[Brian Murray]

I was reviewing an SRU upload the other day where each change in the
package did not have a bug corresponding to it in Launchpad and there
was one bug which covered multiple issues. This is a lot messier than
having one bug per issue being fixed but I wondered why the uploader may
have thought this was okay. Looking at the StableReleaseUpdates wiki
page I think the "Fixing several bugs in one upload" section[1] is
confusing (does it apply to sponsorship?) if not unnecessary.

I'd like to yank out some of the words from that section like "avoid
creating meta-bugs ... will generally be invalidated" and put it in
either Step 2 of the procedure section or in between Step 2 and Step 3.
Additionally, I'd delete the whole "Fixing several bugs in one upload"
section.

If nobody objects to these changes I'll do it next Tuesday.
