Bug Description

== SRU Justification ==

=== Impact ===
Charms written in shell, which is the bulk of charms, cannot make use of the output of this command. Also charms written using the documentation as a guide will not work because the docs say it works this way.

=== Test Case ===
1. juju bootstrap
2. juju deploy --repository /usr/share/docs/juju/examples local:mysql
3. juju deploy --repository /usr/share/docs/juju/examples local:wordpress
4. juju debug-hooks wordpress/0 db
5. juju add-relation mysql wordpress
6. When the db-relation-joined hook window opens up run 'relation-ids'. Affected versions will print out json, while fixed versions will print out a list, something like "db:0\n"

=== Dev fix ===

Fixed in upstream commit 532

=== Regression Potential ===

Medium. Charms may have already been written that are using the broken behavior. They will have to add --format=json but other than that will work fine. This is mitigated by the fact that the official PPA version is already fixed, and many users, including the charm store automated testing suite use that version.

== Original Bug Description ==

Adds format_smart method for RelationIdsCli, which outputs whitespace separated (to be precise, per line) relation idents.

How serious is this bug? Worth updating juju in precise?

I believe it is worth updating in precise:

1) The fix is small and contained
2) It fixes an important deviation in behavior for shell users; prior to this change, output is always json, which is difficult for shell programs to parse without a helper
3) The fixed feature likely is only starting to see experimental usage now, but should become more important for a number of use cases in relation orchestration in the near term

Ok sounds pretty important, though I worry about regressing charms that are written between now and this being released in Ubuntu.

Since it was already merged, I'm moving it to galapagos.
