[PATCH 0/2] clean leftover calls to string_list_remove_duplicates

replace calls to string_list_remove_duplicates with string_list_sort_u.

sorted behavior of &keys_uniq depends on the call to string_list_sort on &keys before &keys is processed to form &keys_uniq, this introduces an edge case where &keys_uniq will not be sorted as expected, follow [1] to reproduce. add string_list_sort_u to &keys_uniq to fix this edge case and ensure future enhancements to the processing logic does not introduce regressions.

[1] run command: cat <<'EOF' >> Documentation/config/add.adoc aa*.b:: aa.b:: EOF from git/ and then make test, this sees one failure when the test compared actual output with sort -u output.

Amisha Chhajed (2):
  sparse-checkout: use string_list_sort_u
  help: ensure &keys_uniq follows sort -u
