style changes: * consistent copyright/license notice formatting * removed hardcoded name of test file (for crlf) * added include guard to cvs_iterator.hpp * removed now useless #includes of "boost/filesystem/exception.hpp" * used ""-style for #includes of non standard headers * renamed class long_name_check to file_name_check (unfortunately we can't rename the .cpp/.hpp files) [SVN r34848]
