"make lint" stumbles over softlinks

[Jeroen T. Vermeulen]

A fix that Jono and I just agreed on involves adding a softlink to the codebase. But it looks as if "make lint" fails to strip the @ that bzr adds to filenames to denote symlinks:

Linting changed files:
  standard_test_template.py@

Traceback (most recent call last):
  File "/usr/bin/pocketlint", line 6, in <module>
    sys.exit(main(sys.argv))
  File "/usr/lib/pymodules/python2.6/pocketlint/formatcheck.py", line 511, in main
    check_sources(sources, reporter)
  File "/usr/lib/pymodules/python2.6/pocketlint/formatcheck.py", line 492, in check_sources
    with open(file_path) as file_:
IOError: [Errno 2] No such file or directory: 'standard_test_template.py@'
