Except that's unsafe.  UNIX supports an atomic "rename", but not
an atomic "copy".  Imagine two instances of TkRemind editing the file
at about the same time...

Right, because TkRemind creates ~/.reminders/100-tkremind.rem.xxx and
renames it to ~/.reminders/100-tkremind.rem which does not molest the
~/.reminders symlink.

It'll be permanent, I'm afraid... there are no plans to change
the way TkRemind edits the file.
