On the following test file (test.py):
Running python -m py_compile test.py return the following error message:
Sorry: IndentationError: unexpected indent (test.py, line 6)
But without a newline on stderr at the end of the message. This causes some problems with scripts that expect a newline and new my particular case with reading stderr on docker where docker just ignore the line if it doesn't end in a newline.
Also, this message differs from the runtime error message:
Would it be possible to at least add in a newline and at best, change the message to be consistent with the runtime error message?
I will trying to look at the code and see if I can write a patch but it will take me some time.

I can confirm that the bugs is demonstrated by copying the text below into a normal unix text file.

This patch adds new line symbol. For some reason py_compile module prints only SyntaxErrors with traceback. All other exceptions are printed with "Sorry:" and in one line.
