Comment(by arctanx):

 The lack of this feature was annoying me so I made some changes to the
 code from 2.4.2 (as I had it handy) to implement cutting off at the
 defined HISTORY_SIZE. The intended behaviour is that it will display logs
 from the most recent to as far back as it can go without either running
 out of logs or the displayed output going over HISTORY_SIZE. If this is
 partway through a log it will chop off the start and put mark it with an
 ellipsis.

 I'm not an experienced C programmer and haven't worked on pidgin before so
 the code is probably quite raw, but it's working fine for me.

 Any suggestions/testing would be much appreciated.
