	There may not be any definition in the GNU Coding Standards, but I
always have seen spaces around unary operators and that has been the
standard (I guess informal) that I was told.  I am not commenting on
whether I like it or not, but I disagree with making this style change.
If we now have `!x' and `~x' scattered throughout the code, I think it is
because we have not been as diligent about maintaining the original style
as we used to be.  To maintain symmetry with the rest of the style, I
think that unary operators should have spaces, contrary to Mark's
proposal.
