Vim, by default, does not expand tabs (leaving tab chars in the file).
This line helps vimmers who does not expand to align with our policy.
It also sets shifts and tab space to 2 columns.

Expand tab is not :retab when you are actually expanding tabs on the
lines you have not written. I am trying to follow your motivation and
explanation here.

So if you see this one, please do not remove it. Although I don't put it
everywhere (katello source base does not have these), it does not hurt
at all.
