Sylvestre LedruandGitHub ff918e4a63 grep: strip trailing (os error N) from file error messages to match GNU (#6) 2026-05-29 22:24:20 +02:00
Sylvestre LedruandGitHub c50c0458cb fix: accept repeated options like GNU grep (#2) 
GNU grep tolerates options given more than once (boolean flags are
idempotent, value options take the last occurrence), but clap rejected
them with "cannot be used multiple times" (exit 2). Set
args_override_self(true) so clap replaces rather than errors; args with
ArgAction::Append (-e/-f/--include/--exclude) still accumulate.

Found by the differential fuzzer (e.g. `grep -e .* -E -n -o -n -x`).

Add a regression test covering repeated booleans, repeated value options
(last wins), and that -e still accumulates patterns.
