When running test-case gdb.python/py-mi-cmd.exp with python 3.13, I run into:

In contrast, with python 3.12 I have:

To make it easier to understand what we're looking at, let's take this out of
the mi interpreter context and use the cli interpreter:
...
$ gdb -q -batch -ex "set trace-commands on" -x gdb.in
+set python print-stack full
+source py-mi-cmd.py
+python pycmd1('-pycmd')
+python pycmd1.invoke (pycmd1, ["exp"])
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "py-mi-cmd.py", line 76, in invoke
raise gdb.GdbError()
gdb.GdbError
gdb.in:4: Error in sourced command file:
Error occurred in Python.
...
Interestingly, this is what we're seeing with both python 3.12 and 3.13.
The difference between the python versions is that:
- with python 3.12 each line is printed by itself, and
- with python 3.13 two particular lines are printed toghether.
With the cli interpreter, that makes no difference, because the '\n' is
interpreted.
But with the mi interpreter, that causes a difference in output because the
'\n' is not interpreted, but rather printed literally.
Fix this by accepting the new output in addition to the old one.
Tested on aarch64-linux.
