progress: stop excessive clearing (
issue4801)
The progress bar was being cleared on every write(), regardless of
whether it was currently displayed. This could foul up the display of
any writes that didn't include a linebreak.
In particular, the win32 mode of the color extension was turning
single prompt string writes into two writes, and the resulting
clear/write/clear/write pattern was making the prompt invisible.
We fix this by insisting that we have shown a progress bar and haven't
just cleared it (setting lastprint to 0).
Conveniently, the test suite already had instances of duplicate
clears.. that are now cleared up.

The file/directory replacement can only be reproduced on
bzr >= 1.4. Merge it back in test-convert-bzr-directories once
this version becomes mainstream.
