This patch implements support for aliases that contain '*' as the destination user. In that case, we replace it with the original user. For example, `*: *@pond` will redirect `lilly@domain` to `lilly@pond`. This is experimental for now, and marked as such in the documentation. The semantics can be subtle, so we may need to adjust them later.
