Avery Pennarun 5c4f710f4e Raw logs contain @@REDO lines instead of formatted data.
This makes them more reliable to parse.  redo-log can parse each line,
format and print it, then recurse if necessary.  This got a little ugly
because I wanted 'redo --raw-logs' to work, which we want to format the
output nicely, but not call redo-log.

(As a result, --raw-logs has a different meaning to redo and
redo-log, which is kinda dumb.  I should fix that.)

As an added bonus, redo-log now handles indenting of recursive logs, so
if the build was a -> a/b -> a/b/c, and you look at the log for a/b, it
can still start at the top level indentation.
