.TP should left-adjust the first line, then put the rest in a right column

[bagder]

A man page section that looks like

.RS
.TP 15
header
a body of text
.TP
header2
another body of text
.RE

Is supposed to have the headers left aligned and the body texts right-aligned in the output. Like this:

header   a body of text
         over many lines
         perhaps

header2  the second body
         over several
         lines

Which roffit does not currently do.
