So, I use bzr.dev on Win32 all the time, and still see progress bars. So
at best, this only happens when running the compiled executable. I
certainly don't see why stdin would inherently be mutated as part of
running under a script. Though perhaps that is true.
More to the point, should we be doing the check on 'stdin'? It seems
like 'stderr' is the most appropriate object, as that is where all the
messages are being sent.
XXX | bzr command
Will hide the progress bar.
Certainly we don't really want to use stdout for the same reason:
bzr command > foo
Would suppress the progress bar as well. Which would make sense for:
bzr command 2>&1 >foo
sort of thing.
So what about this change instead:
