[boost] [string_algo] trimming a range

From: Valentin Samko (boost_at_[hidden])

According to the documentation
http://www.boost.org/doc/html/trim_copy.html
one can not pass a range to boost::algorithm::trim_copy, and
the sequence requirements must be met for the first parameter.

Considering how trim_copy_if is implemented, one can use it with
ranges (for example, with boost::iterator_range). Is there any reason
the documentation requires one to pass a sequence?

Is there any safe and documented way to trim a range, i.e. having two
iterators (begin, end) get a trimmed subrange?

Thanks,
Valentin
