Decrescendo hairpin doesn't cover the ending note for Auftakt

[Yasuda]

A decrescendo mark isn't printed correctly for Auftakt. The hairpin ends on the
right edge of gis in this case.

\relative c'' {
        \partial 2
        b4-. e-. | c (a) c8\> (b a gis | a2\! )
}


This works fine.

\relative c'' {
        \partial 2
        b4-. e-. | c (a) c8\> (b a gis | a4 a4\! )
}
