These patches modify the indentation implementation to use `<p

style=margin-left: n%>'.  Many thanks to Peter and Larry for
suggesting this solution.  Grohtml only uses tables for `.IP' and
related tags when the first operand has a short width.

Similarly, they modify all vertical space code.  By default, grohtml
sets up a style sheet which uses no vertical space between `table',
`pre', and `p' tags.  It forces spaces when it needs them using
`style="margin-top: 1em"'.
