Date/time parsing routines in the email module can crash (instead of returning None) for certain inputs:

>>> email.utils.parsedate_tz('17 June , 2022')
IndexError: string index out of range

This is similar to bpo-45001 (GH-89164)

pythongh-95087: make email date parsing more robust
262ef76 
Similar to bpo-45001 (pythonGH-89164), this makes email date parsing more
robust against malformed input. parsedate_tz() is supposed to return
None for malformed input, but could crash on certain inputs, e.g.

    >>> email.utils.parsedate_tz('17 June , 2022')
    IndexError: string index out of range

Fixes pythongh-95087.
