After a first stab, it seems it is due to an encoding issue
(multibyte v unibyte I guess).  I'm using umlauts and accented
characters and for some reason the encoding on the two pages is
different in planner-update-task(), the test
(planner-tasks-equal-p task-info (planner-current-task-info))
fails (even though they look the (most of the time) same on
screen - most of the time, since I sometimes see the troublesome
\201).  Another effect of this bug is that tasks containing
special characters are not properly carried over (they're
sometimes duplicated, with a different encoding).

Another remark: the documentation for planner-tasks-equal-p()
says that "Return t if TASK-A and TASK-B differ only in terms of
priority and page."  Judging from the implementation that is not
quite true: it returns t if TASK-A and TASK-B have the same value
for category, status, description, link, link-text, plan and
date.  They _can_ have different values for priority and page
(but that is not necessary).

And something else: planner-id-update-tasks-on-page() mentions
`write-file-functions', which is a non-existing variable.
Perhaps write-file-hooks is meant?
