[New-bugs-announce] [issue31330] argparse.RawTextHelpFormatter does not maintain lines separated by more than one newline

[Antony Lee]

New submission from Antony Lee:

The doc for argparse.RawTextHelpFormatter states that it "maintains whitespace for all sorts of help text, including argument descriptions."  But the following example (which outputs "Foo", "Bar", and "Baz", each separated by exactly one empty line) shows that paragraphs separated by more than one empty line will only be separated in the output text by a single empty line.


import argparse
parser = argparse.ArgumentParser(
    prog='PROG',
    formatter_class=argparse.RawTextHelpFormatter,
    description='''\
Foo

Bar


Baz''')
parser.print_help()
