I'm still -0.

Because it affects already existing history and pending merge status, it
is not backward compatible. Because from the start bzr does not have
idea of summary in log messages. May be better make this idea more
straightforward and add some UI (per example, option '-s' for commit
command)? I think, Gnu arch's way is better because it clearly distinct
between summary and log message. Why bzr cannot save summary as separate
metadata of revision?

May I propose to interprete first line as summary *only* if there is no
second line, or if the second line is empty string (or probably contains
only spaces/tabs characters)? In this case 2 varinats of log history:

1:
first line started
and continued on next line

2:
first line

other lines...

So variant 1 will be interpreted as log message *without* summary,
and variant 2 will be interpeted as log *with* summary in first line.
