help: fix output for `hg help -e evolve` wrt 'touch' command

Currently, when running `hg help -e evolve`, the output looks like this on my
screen:

 touch         create successors that are identical to their predecessors
               except

With this change, it looks like this:

 touch         create successors that are identical to their predecessors
               except for the changeset ID
