french beaming incorrectly makes stems longer

[Werner LEMBERG]

Before adding it to the bug tracker I want to check this group's
knowledge whether there is a reason that French beams are longer than
normal:

  \relative c'' {
    r16 f d f
    \override Stem.french-beaming = ##t
    r16 f d f
  }

Looking into scores from French publishers this behaviour seems to be
incorrect.
