Added coverage: an arithmetic shift in `$(( ))`, `(( ))` or `$[ ]` is no longer read as the start of a here-document, so the lines after it are judged as before; the string given to `env -S` or `--split-string` is read as the command env runs; `env -i` is recorded on the command it runs. Tests: test_shellparse_sr2d1.py and eval cases tc-190 and tc-191."
