a momemnt ago, someone reported a problem on IRC regarding
boost::filesystem::path::iterator. He basically has code like

using boost::filesystem::path;
path::iterator i = somepath.begin();
path::iterator j = i++;

That code used to work but stopped working recently.
Now, there is a compiler error saying that the value
returned by i++ is not suitable for constructing j:

error: conversion from `
    to non-scalar type `boost::filesystem::path::iterator' requested

I suspect the change was caused by a recent change to iterator adaptors.

Investigation of the problem revealed that the documenation for
path::iterator says it is a bidirectional iterator while the
implementation uses single_pass_traversal_tag. This looks
wrong to me.
