As a translation admin, I want the initial alignment offered by Special:PageMigration to be balanced enough for me to orient myself in the task of fixing it manually.
First opportunity: align == in the order they appear. Irrespective of (and without changing) splitting, we can align the first source unit having a ^==[^=] to the first "target" unit having a ^==[^=], adding blanks before if needed.
