changeset 3572:fe03c9a476f6

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
