- `datepattern = {^LN-BEG}` - only line-begin anchored default patterns
(matches date only at begin of line, or with max distance up to 2 non-alphanumeric characters from line-begin);
- `datepattern = {*WD-BEG}` - only word-begin anchored default patterns;
- `datepattern = ^prefix{DATE}suffix` - exact specified default patterns (using prefix and suffix);
common filter configs gets a more precise, line-begin anchored (datepattern = {^LN-BEG}) resp. custom anchoring default date-patterns;
As documented at
http://nginx.org/en/docs/http/server_names.html#miscellaneous_names "If
no server_name is defined in a server block then nginx uses the empty
name as the server name." This regex change allows us to match error
output for such a configuration.
The log line added to the tests was lifted from our logs verbatim; it
did not match without the patched regex.

needed since request probably could be not a correct HTTP statement but continue with
all those to match till the end and then injected ", client: VICTIM, server..." thus allowing
injection. We better anchor at the end then
