fix input --until-bytes: now stops at any of given bytes (#10235)

Browse Source 
- this PR should close #10197

# Description
`input --bytes-until` takes a string but used to only terminate on the
first byte of that string. Now it checks for each byte in the string.

# User-Facing Changes
all of the above. No change in documentation needed. New behavior
arguably fits better.

# Tests + Formatting
don't know how to test input
