That's really a rare edge case. I'd just change crop() to cropHTML() as
cropHTML() does the job right in 99% of the use cases. If somebody writes an
extension to have HTML teasers cropped without applying htmlentities before,
he should be able to write his own crop-ViewHelper implementation.

I strongly recommend to implement only the minimal set of features making it a
good product.
