Answering my own post, Thomas Moschny proposed on IRC to add a new 
output chunk type similar to "m" for "more" and "l" for "last". This 
could be named "t" for "ticker" and could include the resting number in 
the payload for the current action. For example the command mtn annotate 
which would need to look for changes in 3000 revisions would output

l8:annotate3:fooe
0:0:t:4:3000
0:0:t:4:2999
...
0:0:t:1:1
0:0:m:1024:<annotate output>...

Now the question for me (who likes to start on that) is how ticker from 
ui.hh/cc could be woven together with automate_streambuf nicely (I could 
think of a few ways, but none real nice, like giving a reference to 
automate_ostream to ticker, ...) so that the ticker is able to output 
its state (and hopyfully before any other real output by the command 
itself happens)?

Thomas.
