A file operand named `-d=` after `--` was rewritten to `--delimiter==` before clap parsing, so cut opened the wrong file. Stop the rewrite once `--` has been seen. Fixes uutils#15806

Fixes #15806.
uumainrewrites a raw-d=argument to--delimiter==before clap parses the command line, so GNU'scut -d=works. It did this for every argument, including file operands after--, socut -d: -f2 -- -d=opened--delimiter==instead of-d=(or failed withNo such file or directory).The rewrite now stops once
--has been seen.Tests
test_equal_delimiter_file_operand_after_double_dash: creates both-d=and--delimiter==and checks thatcut -d: -f2 -- -d=reads-d=. It fails onmainand passes with this change.cargo test --features "cut sort" --no-default-features --test tests: 317 passed.cargo fmt --checkandcargo clippy -p uu_cut -- -D warningsare clean.The issue notes that
sort's-trewrite has the same problem; I've sent that as a separate small PR.I used an AI assistant while working on this; I reviewed the change and the tests myself.
