[Bug python/10826] possibly re-order '^done' message and python script output in MI mode

["pmuldoon at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

I submitted a patch for what I thought would the solution here:

http://sourceware.org/ml/archer/2009-q4/msg00023.html

And Tom reviewed it here:

http://sourceware.org/ml/archer/2009-q4/msg00033.html

Tom quite rightly points out that commands are required to flush the buffer or
emit a newline. And that this should be the same for Python scripts. I decided
to write a hello world command and test if the output was sequenced correctly if
there were multiple writes, and one flush: 

class HelloWorld (gdb.Command):
  """Greet the whole world."""

  def __init__ (self):
    super (HelloWorld, self).__init__ ("hello-world", gdb.COMMAND_OBSCURE)

  def invoke (self, arg, from_tty):
    gdb.write("Hello, World!")
    gdb.write("Lovely weather!")
    gdb.write("What a nice day for a walk")
    gdb.flush()

HelloWorld ()

output:

(gdb) 
python execfile("/home/build/helloworld2.py")
&"python execfile(\"/home/build/helloworld2.py\")\n"
^done
(gdb) 
hello-world
&"hello-world\n"
~"Hello, World!Lovely weather!What a nice day for a walk"
^done


I also tested the case with just a new line at the end, and no flush:

hello-world
&"hello-world\n"
~"Hello, World!Lovely weather!What a nice day for a walk\n"
^done
(gdb) 

So in both cases this works, and no patch is needed. So closing, happily with no
patches needed!
