Macro expansion in hostextinfo->notes_url

Hello,

does anybody know why $HOSTNAME$ in hostextinfo->notes_url expands to 
host name, while $HOSTGROUPNAME$ expands to nothing?

With Nagios 2.10, I am using notes_url in hostextinfo to create an icon 
displayed next to host name.  The icon is clickable and provides 
convenient access to device configuration stored in CVS and available 
via cvsweb.

The following snippet works well:

define hostextinfo {
         host_name   ^sw-.*
         notes_url   /cgi-bin/cvsweb.cgi/XXX/configs/$HOSTNAME$?rev=.
}

XXX denotes site name.  It is the same as the name of Nagios hostgroup 
the host is in.  So the following would be an elegant way to define 
notes_url for gateways on all sites:

define hostextinfo {
         host_name   ^gw-.*
         notes_url 
/cgi-bin/cvsweb.cgi/$HOSTGROUPNAME$/configs/$HOSTNAME$?rev=.
}

However, the resulting URL looks like .../cgi-bin/cvsweb.cgi//configs/...

Is it a bug or feature? ;-)

Thanks,

	Rosta
