log speedup: use only ui.write in changeset_printer.show - ui.status is not very useful, since this code is never executed when ui.quiet is true. - explicitly checking for ui.debug allows a regular hg log to run without looking at the manifest index - the calls to ui.note were converted for consistency

#!/bin/sh

touch a
hg add a

echo %% Should show unknown

hg revert -r 0 --all
