making a TextSpanner not re-print the text after a line break

[Steve Yegge]

I've got a text spanners with a relatively long string for its

#'bound-details #'left #'text property, and the spanner spans

several line breaks.  The result is something like

long spanner text ............... \break

long spanner text ............... \break

long spanner text ......

whereas I'd prefer it to be

long spanner text ............... \break

............... \break

......

I didn't see a way to control this behavior, though.  Did I miss

something obvious?

Thanks,
