Yes, we changed import behavior yesterday. Import now works the same
way as commit does: first it writes the tree structure to the server,
then it writes all the files' contents. Commits have always worked
this way, because it allows the server to detect (and reject) any
out-of-date conflicts as early as possible. (Think about how awful it
would be to commit for 10 minutes, and near the end of the commit have
the server reject an out-of-date file. With this method, the
rejection happens during the first minute.)

The moving dots were added yesterday as well, to both import and
commit. It's nice to give feedback to a waiting user.
