If a long option that accepts an optional argument is given without one, optind is advanced twice, and the following argument is skipped. For example, "pg_waldump --stats --limit 5" skips --limit and interprets "5" as a non-option, so the command complains that it cannot location WAL file "5". The same path also returns BADARG when optstring starts with a colon, even though nothing is missing. To fix, handle optional arguments before the missing-argument code, which then only needs to deal with required arguments. This is a bug fix and could be back-patched, but since this issue went unnoticed for 23 years, I'm not going to bother.
