[PATCH 0/2] clean leftover calls to string_list_remove_duplicates

[Amisha Chhajed <amishhhaaaa@gmail.com>]

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
