bzr handholding: restoring deleted file

[Glenn Morris]

I made a branch with `bzr branch http://...'.

Then I did `rm configure'.

How do I get the damn file back again, like `cvs update' would do?

`bzr update' chirpily says `Tree is up to date'.
`bzr pull' thinks a bit, then says `No revision to pull'.
`bzr merge' fails due to uncommitted changes.
