Module stream 

The input: argv as a slice of words.

Argv is a winnow Stream whose tokens are the words of the command line, borrowed as BStr, so nothing is copied or joined and any byte, NUL included, can appear in a word. A word is never re-split: "a b" is one token, the same as the shell handed it over.

Offsets are counted in bytes as if every word were followed by one separator, so a position inside a bundle of short flags (-vq) is still a single number that shrinks as the lexer reads a letter. That keeps repeat’s “parser must consume” check and error offsets meaningful.
