commit 50af0d77b544fa2a9b68d3c1ca6f40a32e35ac33

    Flesh out the Program run code to cover all cases
    
    Previously the runProgramInvocation impl only covered the common special
    cases that we currently use. In particular it did not support env vars
    or changing the workind directory.
    
    Also change the ProgramInvocation { progInvokeEnv } to allow unsetting
    env vars, not just setting them to new values.
    
    This stuff would be better if we could use createProcess for all cases
    but that doesn't yet support running programs in the foreground with
    proper ctl-C handling (only rawSystem currently supports that).
