minor annoyance

Hi,

When I interrupt (C-c C-c) saving a remember note (e.g. because I
forgot to add something), then the modified wiki/planner pages need
manual tweaking, because half of the saving work had been done already
before the interrupt.  That's not very nice.  No great harm is done,
but it's just annoying, and gives an un-solid feeling to the package.
Yes, saving can take a long time; I think as a first step in the right
direction, the command should collect all its information before
starting to modify any buffers: that removes at least very obvious
cutting interrupt points (where accidental quitting is very well
possible).

Cheers,

Frederik
