Merge r1744980 from trunk:

Save a few bytes in the conf pool.

The directive's names don't need to be duplicated in this pool when parsing the configuration file.

Either they match a known directive name and we can use it directly if needed. Otherwise, it is still possible to make a copy afterwards.
