as() handles wide sub_match objects correctly, fixes #4496

svn path=/trunk/boost/xpressive/; revision=65788
Replacing the use of <iomanip> with <boost/detail/iomanip.hpp> across Boost.
On Linux, GNU's libstdc++, which is the default stdlib for icc and clang,
cannot parse the <iomanip> header in version 4.5+ (which thankfully neither
compiler advises the use of yet), as it's original C++98-friendly
implementation has been replaced with a gnu++0x implementation.
<boost/detail/iomanip.hpp> is a portable implementation of <iomanip>, providing
boost::detail::setfill, boost::detail::setbase, boost::detail::setw,
boost::detail::setprecision, boost::detail::setiosflags and
boost::detail::resetiosflags.

Fix a standards-conformance issue where Xpressive is attempting to
construct an incomplete type (detail::ReplaceAlgo) within a template
definition. This is ill-formed, but only Clang seems to diagnose the
issue.
