Subject: petrol: fix bug with auto-update of 'other' fields.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=f89d7af59fcd9a2fe0c456fbdd2d9ff77541b649;p=plato.git

petrol: fix bug with auto-update of 'other' fields.

If a field is empty, so put it on the list of 'recent'
fields.  Otherwise the calculation of when to update
the "3rd" field gets confused.
