You are passing '/tmp/bzrtest/' for the file list parameter.  That is
equivalent file_list=['/', 't', 'm', 'p', '/', 'b', 'z', 'r', 't', 'e',
's', 't', '/']

If you pass in ['/tmp/bzrtest/'], you will get the results you want.

Pretty much the same as cmd_status does it, if you're trying to imitate
status closely.

bzr_wt = workingtree.WorkingTree.open('/tmp/bzrtest')

for path, k, t, m in bzr_wt.changes_from(bzr_wt.basis_tree()).modified:

    print path

Note that 'delta.TreeDelta.modified' contains files that have only been
modified, not ones that have been renamed and modified.  For details,
see bzrlib/delta.py
