## 4368: rbt post --diff-only no longer works correctly

Reported by: sallan 4 years, 3 months
What version are you running?
RBTools 0.7.4 on Windows.
ReviewBoard version 2.0.18
Perforce 2014.2

What steps will reproduce the problem?

Create a numbered perforce change list with a description.
Use to create a new review request
$rbt post CL Publish review Manually edit the description field in the review request Update the file diffs using --diff-only to leave the description alone$ rbt post --diff-only CL
Note the changes made in the description field in the review request have been replaced with the perforce change list description again.

What is the expected output? What do you see instead?
Using the --diff-only option, I expect my changes made to the description field in the review request to be left in tact. Instead, they are being replaced with the perforce change list description as if the --diff-only option was not used.
What operating system are you using?
MS Windows 7
Attach the debug out from the command.

Description:
Bogus review request to test --diff-only option
I'm adding this comment for Rev 2. Using --diff-only, this text should not appear in ReviewBoard

Oddly enough, it only used the first line and did not include "I'm adding this comment..." text.

Please provide any additional information below.
