[tor-commits] [metrics-lib/master] Looks like blank lines are allowed in v2 statuses.
commit 02fa685e9ca3f0c577fec850d31650a2452f1926
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

Looks like blank lines are allowed in v2 statuses.
For the moment, we still disallow blank lines in all other descriptors.
If this is not correct, we can easily fix that.
