* Start on some tests for <$action-deletefield /> * Only update modified field if we actually delete a field …in the <$action-deletefield /> widget. Fixes a bug where <$action-deletefield foo /> would update the modified field if the "foo" field wasn't present on a tiddler. * action-deletefield: Test when modified does and doesn't exist * Add $timestamp argument to action-deletefield To make it more consistent with other tiddler-manipulating action widgets * Add docs for action-deletefield $timestamp
