issues to verify -> no more releases

[Graham Percival]

Now that the Patchy staging-merge is running ok, it's time to
force the next issue:
  I will not be making any more releases, stable or unstable,
  as long as there are issues to verify relating to a
  previously-released version.

At the time of this writing, this means that if *ANY* issue on this
list:
http://code.google.com/p/lilypond/issues/list?can=7
does *NOT* say "fixed_2_15_28", there will be no release.


Building a release means I need to reboot into a less-useful OS
where I can't work on most of the stuff I need to work on, and it
takes 3-4 hours.  If the lilypond community cannot find
**20 MINUTES** to clear out the old issues to verify, then I see
no reason to impair myself for 4 hours.

This is not a policy decision; it is not open to discussion or
pleading.
