[issue43473] Junks in difflib

[Hubert Bonnisseur-De-La-Bathe]

New submission from Hubert Bonnisseur-De-La-Bathe <hubertbdlb at gmail.com>:

Reading first at the documentation of difflib, I thought that the use of junks would have produced the result 

s = SequenceMatcher(lambda x : x == " ", "abcd efgh", "abcdefgh")
s.get_matching_blocks()
>>> [Match(a=0, b=0, size=8)]

At a second lecture, it is clear that such evaluation will return in fact two matches of length 4.

Would it be nicer to have get_matching_block return the length 8 match ? 

Don't know if it's in the spirit of the lib, I'm just asking.
