Do you mean that the current command is not repeated in history if it 
matches the previous most recent command in the history buffer?

My history looks pretty lengthy, but I do seem to recall a limit.  Also, 
given it isn't recent history I can't look through it and conclude that 
it is complete.

I recall some years ago writing a history patch that allowed it to be 
configured in a couple ways: one being complete history, one being more 
condensed.  I might still have that around if you are interested, but 
I'd have to search for it and I'm sure it has conflicting hunks by now.
