doc branch: provide examples for listing remote tracking branches
The availability of these pattern selections is not obvious from the man pages, as per mail thread <87lfz3vcbt.fsf@evledraar.gmail.com>. Provide examples. Re-order the `git branch` synopsis to emphasise the `--list <pattern>` pairing. Also expand and reposition the `all/remotes` options. Split the over-long description into three parts so that the <pattern> description can be seen. Clarify that the `all/remotes` options require the --list if patterns are to be used. Add examples of listing remote tracking branches that match a pattern, including `git for-each-ref` which has more options. Improve the -a/-r warning message. The message confused this author as the combined -a and -r options had not been given, though a pattern had. Specifically guide the user that maybe they needed the --list option to enable a remote branch pattern selection.
