 Lovely poem -- it's also nice to say something about what
 actually happened :-). The issue tracker is an adjunct to
 the logs, but not a replacement.

  + svn_stream_t *out = svn_stream_from_aprfile (std_out, pool);
 
 A comment explaining why handle returned by
 apr_file_open_stdout() is preferable to the C library stdout
 would help a lot here. I'm guessing it's that the C stdout
 can't trusted to treat data as binary on all platforms,
 whereas the APR version can? But not sure about that...
 

APR never uses stdio. Stdio (i.e. open, fopen, and fdopen) on Win32 is
the only thing that cares about text vs. binary.

Dunno about all APR platforms, but I hope this remains the case
everywhere. If it isn't it's likely an APR bug.
