[New-bugs-announce] [issue43776] Popen with shell=True yield mangled repr output

New submission from mkocher <Michael.Kocher at me.com>:
When using Popen with shell=True, the output of the repr is not particularly user friendly.
When using the form `p = Popen('python --version'.split())`, the output is reasonably output in a user friendly form of `<Popen: returncode: None args: ['python', '--version']>`.
However, when running with `shell=True`, the output is mangled.
For example, trying to run `python --help` via `p = Popen('python --version', shell=True)` yields the following output.
`<Popen: returncode: None args: ['p', 'y', 't', 'h', 'o', 'n', ' ', '-', '-',...>`
The original change appears to be motivated by https://bugs.python.org/issue38724
