[Tim Graham]

New submission from Tim Graham <timograham at gmail.com>:

As discussed in issue30349#msg311684, fnmatch.translate() can produce a pattern which emits a nested set warning:

>>> import fnmatch, re
>>> re.compile(fnmatch.translate('[[]foo]'))
__main__:1: FutureWarning: Possible nested set at position 10
re.compile('(?s:\\(.s:[[]foo\\\\\\]\\)\\\\Z)\\Z')
