minor item : url link in man pages is wrong

[Dennis Clarke]

A man page in libidn2 seems to point to a place that is a 404 whereas
this seems to be what we need :

https://www.gnu.org/software/libidn/libidn2/manual/html_node/

Or something like that.  What I see is :


beta # man -M /usr/local/share/man idn2_check_version
Reformatting page.  Please Wait... done



libidn2                                     idn2_check_version(3)



NAME
     idn2_check_version - API function

SYNOPSIS
     #include <idn2.h>

     const char * idn2_check_version(const char * req_version);

ARGUMENTS
     const char * req_version
                 version string to compare with, or NULL.

DESCRIPTION
     Check IDN2 library version.  This function can also be  used
     to  read  out  the  version  of  the library code used.  See
     IDN2_VERSION  for  a  suitable    req_version   string,   it
     corresponds  to  the  idn2.h  header file version.  Normally
     these two version numbers match, but if  you  are  using  an
     application  built  against  an  older  libidn2 with a newer
     libidn2 shared library they will be different.

     Return value: Check that the version of the  library  is  at
     minimum the one given as a string in  req_version and return
     the actual version string of the library; return NULL if the
     condition is not met.  If NULL is passed to this function no
     check is done and only the version string is returned.

SEE ALSO
     The full documentation for libidn2 is maintained as  a  Tex-
     info  manual.  If the info and libidn2 programs are properly
     installed at your site, the command

          info libidn2

     should give you access to the complete manual.  As an alter-
     native you may obtain the manual from:

          http://www.gnu.org/software/libidn2/manual/


libidn2                Last change: 2.0.4                       1


So https://www.gnu.org/software/libidn/libidn2/manual/  would be better.
