D'oh... only just saw this! So compare-histos has this logic:

if opts.RATIO_DEVIATION:
    paramdefaults["RatioPlotMode"] = "deviation"
if HISTOS[ref][name].isdata:
    paramdefaults["RatioPlotYLabel"] = "MC/data"

I can change this to:

if opts.RATIO_DEVIATION:
    paramdefaults["RatioPlotMode"] = "deviation"
if not HISTOS[ref][name].isdata:
    paramdefaults["RatioPlotYLabel"] = "Ratio"
    if opts.RATIO_DEVIATION:
        paramdefaults["RatioPlotMode"] = "Deviation"

which would use the default labelling for MC-data comparisons, and
"Ratio" or "Deviation" as appropriate for MC-MC (or unknown)
comparisons. Ok? Any problems with doing that?
