filter-out function is first used to discard names ending in
.o with a single simple pattern. The second filter-out function
augments the simple pattern with three literal names, which are
also added to the text argument. This tests an internal hash table
which is only used if there are multiple literals present in both
the pattern and text arguments. The result of both filter-out
functions is the same single .elc name.\n";
