mbilog.cpp was changed in the past to output the absolute date/time. This introduced an additional newline in the output which breaks readability. Output now looks like

[Fri Apr 16 15:43:22 2010
0.260 ] In c'tor of PSelectForOneReferenceQuery
[Fri Apr 16 15:43:22 2010
0.260 ] In c'tor of PSelectForOneReferenceInNtoMQuery
[Fri Apr 16 15:43:22 2010
0.260 ] In c'tor of PSelectForPresentNtoMReferenceQuery

The newline is introduced by the call to ctime(..), which return it by definition.

I would remove this extra newline and replace it with a space character (to separate absolute time from relative time since thread start).

I already verified that my change changes the output to

In T3684 I suggested a review to define some tests cases for logging.
