[PATCH] cli: notmuch address option defaults update

[Tomi Ollila]

When no --output option were given, change default to display senders
only. This is faster and provides useful-enough list of addresses.

When only --count option is given, display senders (in contrary to not
displaying anything).

Document how --count affects to "sort order" a bit more accurately.

Clean up some whitespace in the documentation.

One test updated to have --output=count without sender nor recipient
output option.
---

Some quick updates to the notmuch address interface which I hope will
be considered to be included in 0.19 release. As we are in feature freeze
I hope this gets quick feedback, in any way you desire.
