foreachwikiindblist has a nice feature of prefixing output with the wiki ID. E.g.
frwiki: Checked a total of 300 Flow boards. Of those, 0 boards had an inconsistent title; 0 were identified as fixable.
However, it doesn't do this for stderr.
ERROR: 'वापरपी चर्चा:Dhanesh Shirodcar' JSON content does not have a valid workflow ID.
