[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Matthew Barnett]

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

Another flag? Hmm.

How about this instead: if a scoped flag appears at the end of a regex (and would therefore normally have no effect) then it's treated as though it's at the start of the regex. Thus:

    foo(?i)

is treated like:

    (?i)foo
