errors: restructure formatparse() to clarify conditions a bit

The `similar` list will be calculated only for
`error.UnknownIdentifier`. It was then printed only if `inst.location
is None`, which is true for that exception type, but it's an indirect
condition to rely on.

Also, it looked from the code like it could both report similarities
and print a hint. That would be a little awkward because the
similarity report looks similar to the hint (both are printed within
parentheses). I also added a `elif` to clarify that. I plan to
refactor this more coming patches so the similarity report actually is
a hint.

"""collection of simple hooks for common tasks (EXPERIMENTAL)

This extension provides a number of simple hooks to handle issues
commonly found in repositories with many contributors:
- email notification when changesets move from draft to public phase
- email notification when changesets are obsoleted
- enforcement of draft phase for all incoming changesets
- enforcement of a no-branch-merge policy
- enforcement of a no-multiple-heads policy

The implementation of the hooks is subject to change, e.g. whether to
implement them as individual hooks or merge them into the notify
extension as option. The functionality itself is planned to be supported
long-term.
