Here it is. It's my first patch for subversion, so please bear with me
if I did something stupid.

[[[
Flush stdout after every line that is printed (for most commands, except
for diff and blame).  This is useful when piping svn output into
post-processor tools, e.g. to colorize the output, or simply into tee.
* subversion/svn/diff-cmd.c
  (summarize_func): Flush output after every line printed.
* subversion/svn/status.c
  (print_status): Flush output after every line printed.
* subversion/svn/notify.c
  (notify): Flush output after every line printed.
