Well you didn't expect it to do a checkout too, did you?

Did you dump the .i files in .hg? Or just the ones in .hg/data?

BTW, modern hg uses a slightly different layout by default which
addresses some issues like filesystem case-folding. Which is why the
comments mention .hg/store/. Any time you do a clone over the wire or
with --pull, you'll get this new layout.
