Thank you for the suggestion. In order to remove both the .bzr/
directory and the .bzrignore file, it seems to be necessary to specify

[.]bzr$
[.]bzrignore

in the .Rbuildignore file before calling R CMD build.

This is certainly sufficient in my case, but since the patch is just one
line, perhaps it should be considered for inclusion as well.
