Okay, some UI work needed here to meet these needs, then: it's worth
getting this stuff as desired before making a release. If we need a mix
of behaviours, then a single command line switch is not going to be
enough: the config file will have to contain instructions for what to do
to each histo/bin-range, e.g.

MY_HIST1:0:5 scale=1.3
MY_HIST2 norm=1.0
MY_HIST3 refnorm

?

Hendrik, how would you like it to work (consistently)?
