According to 'git-log' man page '%+b' should insert linefeed "immediately 
before the expansion if and only if the placeholder expands to a non-empty 
string." Here "%b" expands to a non-empty string, thus I expect a linefeed 
before it. Or am I misinterpreting man page somehow?

I want to display '%B', but add colours to '%s'. Thus I have to separately 
include '%s' and '%b', and not just '%B'. I was using '%+s%n%+b' with extra 
colour formatting as a workaround for some time now.
