changeset_printer: display wdirrev/wdirnode values for workingctx

changeset_printer: display wdirrev/wdirnode values for workingctx

Because we want to eliminate "if"s in the default template, it makes sense to
display wdirrev/wdirnode values for now. wdir() is still experimental, so the
output of "log -r'wdir()'" may change in future.
