cfgmaker if_is_ciscovlan option

Hello,

for me cfgmaker doesn't filter "unrouted VLAN"
with this option:
--if-filter='$default && !$if_is_ciscovlan'.
(Tested on MRTG 2.14.3 and 2.15.0)

If I understand it correctly, that
"if_is_ciscovlan" option
filters all vlans include unrouted vlans.
I look at perl code, and I probably found bad regular
expression.
Problem is, that in normal vlans is number directly after
word Vlan,
but in unrouted VLAN is one space between word VLAN a their
number.

There is output from snmpwalk:
IF-MIB::ifDescr.91 = STRING: Vlan1
IF-MIB::ifDescr.92 = STRING: unrouted VLAN 1
IF-MIB::ifDescr.93 = STRING: unrouted VLAN 1002
IF-MIB::ifDescr.94 = STRING: unrouted VLAN 1004
IF-MIB::ifDescr.95 = STRING: unrouted VLAN 1005
IF-MIB::ifDescr.96 = STRING: unrouted VLAN 1003
IF-MIB::ifDescr.97 = STRING: Vlan2
IF-MIB::ifDescr.98 = STRING: unrouted VLAN 2
IF-MIB::ifDescr.99 = STRING: unrouted VLAN 101

If I change regular expression, that it works for me.
It filters normal and unrouted vlans.
This line I replace:
and $$i =~ /^(unrouted )?V(LAN|lan)d+$/);
With this line:
and $$i =~ /^(unrouted )?V(LAN|lan)s?d+$/);

You can find it in cfgmaker by searching of
"unrouted" word.
I'am not perl expert or programmer. Please comment it 

Best regards,

Pavel Ruzicka
