commit f69319ad8ad1dd50f90bbcf5912e11cc8ed3e037
Author: Darren Tucker <dtucker at dtucker.net>
Date:   Sat Jul 23 14:38:22 2022 +1000

    Convert "have_prog" function into "which".
    
    "which" and its behaviour is not standardized, so convert the existing
    have_prog function into "which" so we can rely on it being available
    and what its semantics are.  Add a have_prog wrapper that maintains the
    existing behaviour.
