The word "align" describes how the function actually differs
from find_unique_abbrev, and will make it less confusing
when we add more diff-specific abbrevation functions that do
not do this alignment.
Since this is a globally available function, let's also move
its descriptive comment to the header file, where we
typically document function interfaces.
