Parseable output (was Re: [Locking] svnadmin prints out newline unconditionally.)

It looks fine to me.

But: let me change the subject.

Mike Pilato pointed out a problem with all three commands that display
lock details:

     svnadmin lslocks
     svnlook lock
     svn info wcpath-or-URL

Each of those commands shows the lock-comment field last, because it's
the only one that's potentially a multi-line value.

The problem is that svn's output is always supposed to be machine
parseable. Up till now, the only time we've had to deal with
unpredictable multi-line output is with 'svn log', and the problem was
solved by printing a header saying "N lines", so a parser knows how
many lines of commit-message to slurp up.

So Mike's pointed out that we should probably be doing the same thing
for those three commands -- right? Heck, maybe even a separator line
between objects would help too, just like we do for 'svn log'.

Do others concur?
