I think 'To get the working tree created again holding the last checked 
in files, use "bzr checkout"' is not very clear.  Something like 'To 
re-create the working tree, use "bzr checkout".' seems better to me.  I 
don't think it's necessary to point out that running bzr checkout will 
restore all files to their last-committed state.  But in any case, 
"check in" is not a term we use.

I don't think it makes sense to capitalize "Export" in "Note: Export of 
tree with..."

I think your simplification of selected-file commits oversimplifies.
