Improve description guessing when --summary is used.
Review Request #8092 — Created March 31, 2016 and submitted — Latest diff uploaded
If the summary is passed on the command line but the description is guessed
from the commit message, the first line of the commit message would be lost.
This change improves that by concatenating the summary and description back
together if the summary line isn't being used for the review request.Based on work by Alexander Goncahrov at https://reviews.reviewboard.org/r/7806/
Ran unit tests.
