3.0.8: Request log filename for virtual servers with a hythen

[Lai Fu Keung]

Hi,

I configured my 3.0.8 to have a separate log for all requests based on virtual servers. That is, in radiusd.conf, I uncomment the following line:

requests = ${logdir}/radiusd-%{%{Virtual-Server}:-DEFAULT}-%Y%m%d.log

For "inner-tunnel" virtual server, the filename turns out to be 
"radiusd-inner----tunnel-20150424.log" (3 more hythens between "inner" and "tunnel").

The filename was fine in 3.0.7.

Bug? My mistake?
