Before:
  call ale#assert#SetUpLinterTest('pyrex', 'cython')

After:

Execute(The default cython command should be correct):
  AssertLinter 'cython', ale#Escape('cython')
  \   . ' --working %s:h'
  \   . ' --include-dir %s:h'
  \   . ' --warning-extra'

Execute(The cython executable should be configurable):
  let b:ale_pyrex_cython_executable = 'cython_foobar'

  AssertLinter 'cython_foobar', ale#Escape('cython_foobar')
  \   . ' --working %s:h'
  \   . ' --include-dir %s:h'
  \   . ' --warning-extra'

Execute(Additional cython options should be configurable):
  let b:ale_pyrex_cython_options = '--foobar'

  AssertLinter 'cython', ale#Escape('cython')
