Mattflaschen has uploaded a new change for review. (
https://gerrit.wikimedia.org/r/342979 )
Change subject: Prevents duplicate filter names
......................................................................
Prevents duplicate filter names
Explicitly block two filters in the same group from having the same
name.
Before, it would be left to registerFilter, which would just cause
the second one to win.
Also, avoid a getFilter warning when the filter does not exist.
Finally, a minor related doc fix.
