[New-bugs-announce] [issue42790] test.regrtest outputs to stdout instead of stderr

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

unittest outputs progress and summary to stderr, but test.regrtest outputs it to stdout. Except that it outputs progress to stderr if option -W is used.

It caused some problems with test_curses, because curses uses stdout, and when re-attach it to other terminal or file we can lose the regrtest output. It makes the code more complicated.
