Ok @chris, it's removed.
I think I went about updating this in the wrong way.
First, i made the change on my 3460-wip branch
Then I changed over to my squashed branch : CLC-3460-acting-as-updates-first_login_at
Then I tried to merge in changes from the wip branch:
git merge CLC-3460
Which gave me a conflict.
So, I ended up deleting my squashed branch, and created it from my wip branch
git checkout 3460-wip
git checkout -d CLC-3460-acting-as-updates-first_login_at
then I created the squashed branch again:
git checkout -b CLC-3460-acting-as-updates-first_login_at
had to rebase it again
git rebase -i ets/master
squashing my 50 commits again into one commit and then re-adding the original comment.
I'm sure there's a better way to go about this.  Please let me know how you would have done it.

Anyway this pull request has been updated with the long comment removed.  I just did it in a lame kind of way.
