evolve: indentation change for making next patch more legible

In the next patch: "evolve: use repo._bookmarks.recordchange instead of
repo._bookmarks.write" we need to add a transaction in the rewrite function.
To do so adds an indentation level and makes the patch harder to review.
This patch makes the indentation change so that the next patch is easier to
review.
