If I separately get the working tree, export it sans Subversion files,
and attempt to 'bzr init && bzr add', a related error occurs:

=====
bzr> init .

added "testset/filenames/files/ .tif"
added "testset/filenames/files/".tif"
added "testset/filenames/files/'\ "
Invalid entry name: '\

=====

The file entries are deliberately unusual; part of the purpose of the
program is to test for unusual stuff in a software package.

Is this a bug in Bazaar? Why should Bazaar reject filenames that are
valid for the filesystem?
