Problem

parse_key_value VRL function failed with the following real world linux auth log example:

parse_key_value!("TTY=unknown ; PWD=/ ; USER=postgres ; COMMAND=/usr/pgsql-10/bin/psql;", key_value_delimiter: "=", field_delimiter: ";")

I'm getting could not parse whole line successfully error

It is successfully parsed same string but with removed delimiter ";" at the end of string:

parse_key_value!("TTY=unknown ; PWD=/ ; USER=postgres ; COMMAND=/usr/pgsql-10/bin/psql", key_value_delimiter: "=", field_delimiter: ";")
