bad vertical spacing with @item and @example

[Werner LEMBERG]

Consider the following minimal example:

  \input texinfo

  @setfilename yyy

  @table @asis
  @item High-resolution device @code{ps}

  @example
  @group
  shell> echo "hell world" | groff -Z -T ps
  @end group
  @end example

  @end table
  @bye

and process it with texi2dvi.  The vertical spacing is extremely bad.
Actually, the spacing can become even worse so that the lower line
protrudes the upper one (I have such an example but it's difficult to
extract a small example).
