Note that syslog-ng strings use '\' as an escape character, just like in
C, so you need to escape \\ to produce a single '\' character in the
regexp.

I know this is bad, but changing the quoting style is not really
possible without breaking a lot of people's configuration files.

"{^[0-9a-zA-Z\\-]+\\.r[0-9]{2}\\.([0-9a-zA-Z\\-]+)$}"

Maybe a note in the documentation about this would be useful. Ccing the
doc. team about this.
