Thomas E. Dickey 027d0c57c4 ncurses 5.9 - patch 20150516
+ amend change to ".pc" files to only use the extra loader flags which
  may have rpath options (report by Sven Joachim, cf: 20150502).
+ change versioning for dpkg's in test-packages for Ada95 and
  ncurses-examples for consistency with Debian, to work with package
  updates.
+ regenerate html manpages.
+ clarify handling of carriage return in waddch manual page; it was
  discussed only in the portability section (prompted by comment on
  Stack Overflow forum):

<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
If you turn off the menu option <STRONG>O_ONEVALUE</STRONG> (e.g., with
<STRONG>set_menu_opts</STRONG> or <STRONG>menu_opts_off</STRONG>; see <STRONG><A HREF="menu_opts.3x.html">menu_opts(3x)</A></STRONG>), the
menu becomes multi-valued; that is, more than one item may
simultaneously be selected.
In a multi_valued menu, you can used <STRONG>set_item_value</STRONG> to
select the given menu item (second argument <STRONG>TRUE</STRONG>) or dese-
lect it (second argument <STRONG>FALSE</STRONG>).
</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
The function <STRONG>set_item_value</STRONG> returns one of the following:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno</STRONG>).
<STRONG>E_REQUEST_DENIED</STRONG>
The menu driver could not process the request.
