The add_patterns_from_input() function was introduced at 6fb705ab
(sparse-checkout: extract add_patterns_from_input(), 2020-02-11) and
then modified by 00408ade (builtin/sparse-checkout: add check-rules
command, 2023-03-27). Throughout its life, it either allowed to
read patterns from the file (before 00408ade, it only allowed the
standard input, after 00408ade, an arbitrary FILE *) or from argv[],
but never both. However, when we read from a file, the function
never checked that there is nothing in argv[] (in other words, the
command line arguments have fully been consumed), resulting in
excess arguments silently getting ignored.
This caused commands like "git sparse-checkout set [--stdin]" and
"git sparse-checkout check-rules [--rules-file <file>]" to silently
ignore the rest of the command line arguments without reporting.
The fix finally makes the --end-of-options handling for this
subcommand also work, so add test for it, too.
