[New-bugs-announce] [issue30927] re.sub() does not work correctly on '.' pattern and \n

[Robert]

New submission from Robert:

When running the command

    re.sub(r'X.', '+', '-X\n-', re.DOTALL)

you get '-X\n-' instead of '-+-'.

Curiously findall works correctly:

    re.findall(r'X.', '-X\n-', re.DOTALL) => ['X\n']
