Well, you don't have a text, tweakable at it's own, but a
_DynamicTextSpanner_ with some text.
In close to all cases you wouldn't want a working X-offset affecting
the _whole_ DynamicTextSpanner.
Rather you want the left text moved (but the dashed line adjusted
accordingly, leaving the right bound in place)

Therefore we have the bound-details-property:

\fixed c' {
  \override DynamicTextSpanner.bound-details.left.padding = -3
  c4 \cresc c c c |
  c4
  c c c \!
}

Ofcourse, you could set right.padding as well, if desired, etc
Several line-spanners act similar.
