Even when working in gdb itself, you have to be very careful touching anything that affects output or you will cause massive testsuite failures (I speak from experience...)  Implementing this in lldb would not be a simple task.  The amount of effort it would require would be much more productively spent adding test cases to the extant test suite.
I speak from experience as well - I know precisely what you're talking 
about, but is it really *that* bad? It's too bad this couldn't have been 
a goal from the start. c'est la vie
