`man', at least on Debian 3.1, will treat a paragraph beginning with
a period specially _even_ if there's an \fB or similar escape
sequence before the period. Therefore, man_rdaddctrl() now doesn't
clear the QUOTE_INITCTRL flag just because it generated some text;
instead, its call sites clear the flag when the _type_ of generated
text is appropriate for this. This should remove an error from the
`lns' man page (utils/lns/lns.but), which was where I noticed the
problem.
