gh-141570: can_colorize: Expect fileno() to raise OSError, as documented (#141716)
In Fedora, we've been given a slightly incomplete reproducer for a problematic
Python 3.14 color-related change in argparse that leads to an exception when
Python is used from mod_wsgi: https://bugzilla.redhat.com/2414940
mod_wsgi replaces sys.stdout with a custom object that raises OSError on .fileno():
8460dbfcd5/src/server/wsgi_logger.c (L434-L440)
This should be supported, as the documentation of fileno explicitly says:
> An OSError is raised if the IO object does not use a file descriptor.
https://docs.python.org/3.14/library/io.html#io.IOBase.fileno
The previously expected exception inherits from OSError,
so it is still expected.
