Melisma should end with manual beam

[Michael Käppler]

Hi all,
following example:

\relative c' {
 \autoBeamOff
 f2 \melisma f' ~ f4 [ \melismaEnd es8 d ] c4 b
}
\addlyrics { kom -- men }

How can I let the melisma end >with< the beam, like this:

f         f    es d
kom -      men__

Thanks for suggestions,
Michael
