It will do as well. (I have to combine several nearby changes to a
hunk, like "diff -c3" and "diff -u" do, but I can easily do this
myself in a linear pass over the list of changes.)

Also, it doesn't matter whether the return value is a linked list of
'struct change' or an array of 'struct change' - any of these will do.
