I suggest to add week instead of month, as the duration of the former is
more stable and [1;52[ range is still readable.

Then, my examples weren't clear. It is useful to have a list of formats
when using fractional time as the unit used may change:

                          1.2 d    or    1.2 h

I think a plist would be clearer. More on that below.

Shouldn't it be:

(org-add-props (concat (make-string l ?*) " "
                       (org-minutes-to-clocksum-string time)
                       (make-string (- 16 l) ? ))

This is not about your patch, but while you're working in this area: in
documentation, it should be "Org mode".

Ok, for backward compatibility. Note that, for a major release (8.0),
such changes are acceptable even without it.

There, I think we would benefit from using a plist. Indeed,
a two-element list might mean that duration should be expressed in days
and hours instead. Also I suggest to report duration targeted at missing
format strings to the smaller unit. So:

  '(:day nil :hour "%d" :minute ":%02d")

will be the equivalent of the current default format string. Then we can
specify that "%d:%02d" is still available but should be deprecated.

It would also allow to skip months/weeks.

Good idea.
