• 98992641 - Make pre-commit happy
• 5f108b58 - Insist on pre-commit success

Compare with previous version

Note that the commit that adds logging to failed afterInit commands changes e.g.

Command foo not found.
iocsh Error: Break

to

Command foo not found.
iocsh Error: Break
afterInit: Command 'foo' failed to run

The failed commands are logged already, but not explicitly as ones run by afterInit.
