absorb: make it explicit if empty changeset was created
If the config rewrite.empty-successor=skip is set, a message "became empty and
was dropped" is shown if the changeset became empty. If the config
rewrite.empty-successor=keep is set, absorb may create changesets even if they
became empty. It’s probably a good idea to make that explicit. Therefore the
message is changed to be a combination of both: "became empty and became ...".
Repeating the word "became" is not very elegant. This results from the fact
that "became" was and is overloaded to indicate both the change from non-empty
to empty and the successor relation. In the combinated message, both meanings
are used in one sentence.
