subtree: don't let debug and progress output clash

Currently, debug output (triggered by passing '-d') and progress output
stomp on each other.  The debug output is just streamed as lines to
stderr, and the progress output is sent to stderr as '%s\r'.  When
writing to a file, it is awkward to read and difficult to distinguish
between the debug output and a progress line.  When writing to a
terminal the debug lines hide progress lines.

So, when '-d' has been passed, spit out progress as 'progress: %s\n',
instead of as '%s\r', so that it can be detected, and so that the debug
lines don't overwrite the progress when written to a terminal.
