Some IMAP servers send an extra blank line after the counted data of a
literal.
imaplibmistook that blank line for the response trailer,lost track of the real continuation, and aborted with an "unexpected
response" error on the next command. Such a blank line is now skipped.
This revives the fix from the closed PR #26701, adding the regression
test it lacked.
