[Bug] Second run of "Upgrade all" actually downgraded after first one was stopped with Ctrl+C

[venimus]

What You Are Seeing?

I had chocolatey 0.10.8 installed, the latest version available was 0.10.10

I started "upgrade all" but on the prompt to confirm running the post-install script I pressed Ctrl+C so I can rerun it with "-y" parameter I forgot.
After the second run, cocolatey removed an incomplete installation and installed 0.10.7

What is Expected?

Remove latest incomplete install, not the current one. Keep the current version intact.

How Did You Get This To Happen? (Steps to Reproduce)

1. Have outdated choco 0.10.8 installed (upgraded from 0.10.7 some time ago) when there is a new version (0.10.10) available.
2. Start upgrade all (without -y)
3. On the prompt "Do you want to run the script?([Y]es/[N]o/[P]rint):" Press Ctrl+C
4. Run upgrade all with -y param

5. 0.10.8 is removed and reverted to even older version

6. I checked that to be sure. 3-rd run it installed the latest chocolatey

Control+C can cause erratic behavior. Maybe typing N would have been a better option?

[ferventcoder]

Right now it's erratic but not necessarily a bug - we do need to get better about handling Control+C though. I am going to add this as a duplicate of one or more of the other Control+C known issues

[venimus]

I guess "no" will just stop the current script only. I didn't want to continue with the rest installs. May be an option "stop" would be good enough for bulk installs

[AdmiringWorm]

@ferventcoder perhaps another option could be added to the the prompt?
Something along the line of Abort Update (or stop as @venimus suggest), if only one package would be upgraded, it would be essentially the same as No though.

[ferventcoder]

I think it may not be a bad idea to have an Abort, which would essentially stop everything in progress for the whole run instead of just that one.

Global abort on Ctrl-C gets my vote.
