Choosing "Cut" on a cell in the Spreadsheet results in that cell inheriting the
default formatting and losing any generalized changes that were made to the
document, for example through Select All and imposing a new font on the whole
document.  In my specific case, I've Selected All and changed the document font
to Baskerville rather than the default Bitstream Vera.  When I Cut data from a
cell, this cell formats new data in Bitsream Vera.  The cell also loses
alignment settings and font size settings.  I'm presuming it's a fault that
would remove all user-specified formatting from the cell, not just those formats
I've mentioned here.  The data cut from the cell retains all this info as it
should however.
