BGPmon regex

I'm not familiar with BGPmon but your symptoms sounds like typical programming issue.

The '\' is stripped probably due to a "Stripslashes" function in the code. So by doing double '\\' you kinda 
trick the code into only doing the first one.

I don't really know of any way around this.
