Multiple man(7) .IP and .TP fixes started during p2k10:

Affecting both -Tascii and -Thtml:
* The .IP HEAD uses the second argument as the width, not the last one.
* Only print the first .IP HEAD argument, not all but the last.

Affecting only -Tascii:
* The .IP and .TP HEADs must be printed without literal mode,
but literal mode must be restored afterwards.
* After the .IP and .TP bodies, we only want term_newln(), not
term_flushln(), or we would get two blank lines in literal mode.
* The .TP HEAD does not use TWOSPACE, just like .IP doesn't either.
* In literal mode, clear NOLPAD after each line, or subsequent lines
would get no indentation whatsoever.

Affecting only -Thtml:
* Only print next-line .TP children, instead of all but the first.

OK kristaps@ on the -Tascii part; and:
"Can you work this into man_html.c, too?"
