Nice connection!

I just checked out the Google Docs spreadsheet behavior.  I assume that it
mimics the interfaces of other popular spreadsheet programs, though I don't
know that for sure.

  * <enter> and <shift><enter> both save and exit the cell.
  * <control><enter> and <cmd><enter> both insert a newline.
  * <esc> cancels the change and exists the cell.

I haven't seen anyone object to Matthieu's suggested behaviors for <enter> and
<esc>, which are consistent with both behavior and general OS gui conventions,
so I think we may have achieved consensus there.

What's left is the basically irrelevant issue of how to insert a newline
that's going to be turned into a space later anyway.  My inclination is to
supply a patch which simply does not support the insertion of newlines.  If
that results in user confusion and support inquiries, a binding for
<modifier><return> can be added later.
