It should be the regular 80 characters wrap

[ConorMacBride]

Pytest should be automatically detecting the terminal width and setting the width of its own output to that, which can be >80 characters. Most, if not all, terminals will already wrap the text (and alternatively, I don't think we should be truncating the output of pytest-mpl either). The output shown looks like pytest was run in a small terminal window, with the window resized after running. I will close this but feel free to reopen if I have missed anything. Thanks :)
