[issue41664] re.sub does NOT substitute all the matching patterns when re.IGNORECASE is used

[Matthew Barnett]

Matthew Barnett <python at mrabarnett.plus.com> added the comment:

The 4th argument of re.sub is 'count', not 'flags'.

re.IGNORECASE has the numeric value of 2, so:

    re.sub(r'[aeiou]', '#', 'all is fair in love and war', re.IGNORECASE)

is equivalent to:

    re.sub(r'[aeiou]', '#', 'all is fair in love and war', count=2)
