The sort_stdin() helper allocates an input buffer and a memory pool for the list of lines, but returns without releasing either. Discard the pool and release the strbuf after printing the sorted lines.
Add a test for the sort subcommand to t0071. The existing test only exercises the test subcommand, leaving these leaks undetected by the regular leak-sanitized test suite.
