text_only in geom_labelsegment

[Close-your-eyes]

Hey ho!

When setting text_only = TRUE in geom_labelsegment, then the label is actually shorter then defined by x, y, xend, yend (lines at the ends are ommitted). (It is shorter due to length of the text.)
Is it possible to force label size to the defined limits? If the labeltext is shorter, then ends should be white; if the labeltext is longer linebreaks my be forced.

Could such feature be added in case it does not exist yet?

Thank you.
