hgview #19398 improve "Annotate" view : show previous revision number [open]

The main purpose of the "Annotate" view is to be able to go beyond what 'hg annotate' shows; i.e. to know the previous revision of a modified block. But for now, the "Annotate" view shows the current revision, hence giving no access to the revision of the deleted parts of a bigger modified block.

To make this "Annotate" view work as expected, I guess that * either we will have to disable the grouping of a block, and show removed and added parts separately. This might be tricky though; * or we maybe use the previous revision and show these revision numbers only in the "Diff mode".
