rebase: tweak description of inmemory working even w/ dirty working dir

One of our users was confused because they read this, and then attempted to run
`hg rebase` with a dirty working directory, and it still complained. The reason
was that they were attempting to rebase the commit they currently had checked
out, which (at least with evolve workflows enabled) involves updating the
working directory to be based on the newly rebased commit.
