RFC: bzr info layout comments

[Jari Aalto]

"bzr info" currently displays:

    Location:
     light checkout root: file:///usr/share/emacs/site-lisp/
      checkout of branch: file:///root/var/work/site-lisp/

    Related branches:
      parent branch: file:///usr/share/emacs/site-lisp/

    Format:
           control: Meta directory format 1
      working tree: Working tree format 3
            branch: Branch format 5
        repository: Knit repository format 1

        ...

Personally I find this listing difficult to read, because the lines are
not started "left to right", but are rugged. Would it be possible to
to consider left-sticky layout, something like:

    Location:
      light checkout root: file:///usr/share/emacs/site-lisp/
      checkout of branch : file:///root/var/work/site-lisp/

    Related branches:
      parent branch      : file:///usr/share/emacs/site-lisp/

    Format:
      control            : Meta directory format 1
      working tree       : Working tree format 3
      branch             : Branch format 5
      repository         : Knit repository format 1
    | |                    |
    | |                    Same column
    | Same column
    Same column

The colon is important to keel for backends that interpret this information.
