Support pointers to structs in std.range.put().

http://www.dsource.org/projects/phobos/changeset/2008

I'm getting a tad worried that we embrace everything that could possibly work under the ranges juggernaut. Each decision in part is justified (delegates, sealed ranges, opApply, now pointers) but at the end of the day we should clarify a charter. For example until yesterday I had no idea and no intuition that pointers to output ranges should be supported. What's next? Pointers to input ranges? etc.

I'm not saying we need to eliminate something from this diff or the current definition. But a discussion about the ranges' charter would be in order.

  I see where you're coming from, but I fixed this because someone was
annoyed that it used to work and considered it a regression, and the
problem wasn't in any "real" code but in a constraint being
unnecessarily strict.  Pointers to structs fully support type compile
time interface of an output range w/o any changes (besides in template
constraints) to any code that assumes it's getting a struct by value.

Thanks David.

My code works with latest dmd :)
