Comment 17 for bug 1921658

@seyeongkim hi, I'm working on sponsoring your patch right now.
I had to do some minor fixes in it:
1. Since we're adding delta in relation to Debian we should change version number to reflect that (e.g. 7.0-4ubuntu1).
2. The launchpad bug number has to follow the convention for the automation to correctly pick it up and close the bug automatically afterwards (i.e. LP: #1921658 and not "Closes: #1921658).
3. The patch header did not need the "+" signs in the beginning of the line.
4. There was a descriptive commit for one of the lines you backported (static int *local_prompt_newlines;) which you skipped. I think it should also be part of the backport as it explains why the variable is there in the first place.

I'll update this bug if needed.

Thanks for the patch Seyeong!
