[issue19964] '?' is always non-greedy

[Sworddragon]

New submission from Sworddragon:

>From the documentation: "The '*', '+', and '?' qualifiers are all greedy;"

But this is not the case for '?'. In the attachments is an example which shows this: re.search(r'1?', '01') should find '1' but it doesn't find anything.
