Shouldn't code button's geometry, but rather let it adapt to the label

Using rtm 106 on krillin

EditAlarmPage.qml contains that code

" Button {
        id: _deleteAlarmButton
...
        width: units.gu(17)
...
        text: i18n.tr("Delete alarm")
..."

or that width is not enough in some locale which leads to a small button with a truncated string, why not just deleting the width and letting the button adapts to the label? (that's confirmed to work in e.g a french locale)
