The name originally meant to mean "to which element of the array
dir_struct.exclude_list[] are we adding this entry?" but I agree
"el" that stands for ExcludeList would be a better name.
Often we use "el" (or "elem") for elements of an iterable we are
iterating on in a loop, and the name of the iterable does not have
to be EsomethingLsomething, by the way. Because no existing use of
"el" in this file is of that kind, I do not think this change
introduces new confusion to the code.
