For most edits, the IRC recent changes feed provides both the revision ID of the edit and the revision ID of the previous edit, via the 'diff' and 'oldid' parameters in the URL given for the edit.
However, when a new page is created no revision ID is provided. Obviously an 'oldid' cannot be provided as there is not one, but it should be possible to add the revision ID. Currently clients wishing to know the revision ID of the first edit to a page have to use the API instead, or use the very kludgy trick of inferring it by incrementing the revision ID given on the previous line.
Note that the 'rcid', where enabled, is provided in both cases, however this number is no good except for patrolling/sighting pages.
Should be fixed in r44406.
