evolve: add -i flag to amend command

The -i flag was missing because it is not a global flag of the commit command.
We can't make it a global flag yet as it is used in many places where it would
not be appropriate so we just add it for this occurrence.
Also, we only want to add it when commit supports it (otherwise it wouldn't
work with older versions of mercurial)

+  
+      Commits a new changeset incorporating both the changes to the given files
+      and all the changes from the current parent changeset into the repository.
+  
+      See "hg commit" for details about committing changes.
+  
+      If you don't specify -m, the parent's message will be reused.
+  
+      Behind the scenes, Mercurial first commits the update as a regular child
+      of the current parent. Then it creates a new commit on the parent's
+      parents with the updated contents. Then it changes the working copy parent
+      to this new combined changeset. Finally, the old changeset and its update
+      are hidden from "hg log" (unless you use --hidden with log).
