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>
These functions extract the complex character and rendi-
tion from the current position in the named window into
the <STRONG>cchar_t</STRONG> object referenced by wcval.
</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
No errors are defined in the XSI Curses standard. This
implementation checks for null pointers, returns ERR in
that case. Also, the <EM>mv</EM> routines check for error moving
the cursor, returning ERR in that case. Otherwise they
return OK
Functions with a "mv" prefix first perform a cursor move-
ment using <STRONG>wmove</STRONG>, and return an error if the position is
outside the window, or if the window pointer is null.
</PRE>
<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
Note that all of these routines may be macros.

<H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
These functions are described in the XSI Curses standard,
Issue 4.
