library/array.m:
Add uint versions of most of this module's operations.
NEWS.md:
Mention the new operations.
library/edit_distance.m:
Use the new array operations to eliminate some casts.
library/edit_seq.m:
Minor style fix.
tests/hard_coded/array_gen.{m,exp}:
tests/hard_coded/array_test_2.{m,exp}:
Extend the tests of array.m's operations to the corresponding uint
versions. Expect the output for the new versions.
tests/hard_coded/array_resize.m:
tests/hard_coded/array_shrink.m:
Extend the tests of array.m's operations to the corresponding uint
versions, but generate output only if their results differ from the
original int versions. (They don't differ.)
tests/hard_coded/array_primitives.m:
Style fixes.
array.resize/4 has inconsistent behaviour across backends if its first argument
is negative; make it throw an exception if the first argument is negative.
library/array.m:
As above.
NEWS:
Announce the change.
tests/hard_coded/Mmakefile:
tests/hard_coded/array_resize.{m,exp}:
Add a more extensive test case for array.resize.
