[issue14156] argparse.FileType for '-' doesn't work for a mode of 'rb'

[Matt Joiner]

New submission from Matt Joiner <anacrolix at gmail.com>:

If an argument of '-' is handled by argparse.FileType, it defaults to sys.stdin. However a mode of 'rb' is ignored, the returned file object does not work with raw bytes.
