I think the question becomes something along the lines of "are there
situations where this information is totally superfluous, and thus
should simply not be calculated?" The 'svn list' case in non-verbose
mode is one of these situations, and thus it seems like adding a
little more complexity makes sense. I haven't looked too closely at
the do_status case, but if there are situations where the extra work
is causing a noticable usability problem (like it does now with svn
list and large directories) I'd probably be in favor of adding this
kind of option to the interface.

I do agree though, looking in to speeding things up in the general
case is also good, but it's kind of hard to beat "just don't do it at
all" in terms of CPU and bandwidth used.
