juju get <charm> displays description strangely when yaml uses | or > for multiline string literals

[Jay R. Wren]

I'd like to be able to use | or > in the description field of a charm config.yaml

https://en.wikipedia.org/wiki/YAML#Newlines_preserved

If I use >, the output because quoted and has junk after the end:

output of juju get charmstore:

charm: charmstore
service: charmstore
settings:
  listen-port:
    default: true
    description: This is the tcp port on which the charmstore server will listen for
      connections.
    type: int
    value: 8080
  source:
    default: true
    description: 'Branch from where to get charmstore. Possible values are any branch
      names listed at github.com/juju/charmstore.

'
    type: string
    value: master
  use-local-mongo:
    default: true
    description: 'This is a flag which will trigger install of mongodb-server as part
      of this charm. The charmstore server will use this local mongodb instead of
      a related mongodb. With this option set to true, no mongodb relation will be
      required for this charm to function.

'
    type: boolean
    value: false

If I use | it is even worse:

charm: charmstore
service: charmstore
settings:
  listen-port:
    default: true
    description: This is the tcp port on which the charmstore server will listen for
      connections.
    type: int
    value: 8080
  source:
    default: true
    description: 'Branch from where to get charmstore. Possible values are any branch

      names listed at github.com/juju/charmstore.

'
    type: string
    value: master
  use-local-mongo:
    default: true
    description: 'This is a flag which will trigger install of mongodb-server as part

      of this charm. The charmstore server will use this local mongodb

      instead of a related mongodb. With this option set to true, no

      mongodb relation will be required for this charm to function.

'
    type: boolean
    value: false

A work around is to use a literal all on one line. The charm author should not have to go through such hoops to get nice output.
