Doc formatter reformats correct docstring

[probicheaux]

with docformatter 1.4, command docformatter --wrap-summaries 100 --wrap-descriptions 100
the following docstring

"""hello yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet -v
"""

gets transformed to

"""hello yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet
-v."""

which is fine (correct), but then if I run docformatter again, the correct string incorrectly becomes

"""hello yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet.

-v.
"""

Proposing this patch, which supposes that parameter lists in the description usually should have a one line description preceding them
