You should explain why you need that, when the previous patch was
already about removing whitespaces around addresses. I finally
understood that this was needed because alias expansion comes before
sanitize_address, but the commit message should have told me that.

Actually, once you have this, PATCH 6/7 becomes useless, right? (at
least, the test passes if I revert it)

It seems to me that doing this space trimming just once, inside or right
after split_at_commas would be clearer.
