Comment 11 for bug 1556302

The *downside* of reverting our custom patch is that end-users are used to all their personal customization of applications from $HOME working; i.e. currently, when anyone runs vim, emacs, bash, etc. under sudo, any ~/.WHATEVER customization they have will be retained. This is different than, essentially, all other UNIXes, and the fix for this bug would undo that, to put us back in line with all other UNIXes - but would result in behavior change for users, where e.g. 'sudo vim' would not pick up any of their ~/.vimrc configuration (or ~/.emacs.d for emacs, etc...)

Thus, this change, if we do make it, probably should only be done to Eoan and not SRUed.
