svn path=/trunk/boost/iostreams/; revision=43799
Replaced all occurrences of non-ASCII copyright symbol with '(c)' for people using non-ASCII code pages

svn path=/trunk/libs/iostreams/; revision=43992
removed misspelled mimte-type property

svn path=/trunk/boost/iostreams/; revision=44532
Quote href values - our tools don't support unquoted values.

svn path=/trunk/libs/iostreams/; revision=45283
made tee work with input streams (fixes #791)

svn path=/trunk/boost/iostreams/; revision=45752
fixed unused params warnings

svn path=/trunk/boost/iostreams/; revision=45753
fixed #1727

svn path=/trunk/libs/iostreams/; revision=45755
removed unreferenced param warnings

svn path=/trunk/boost/iostreams/; revision=45775
fixes (I hope) the first warning in #1875

svn path=/trunk/boost/iostreams/; revision=45781
added 'x' prefix to several function and type names, to prevent them from being renamed by the preprocessor when Z_PREFIX is defined (fixes #1870)

svn path=/trunk/boost/iostreams/; revision=45783
disabled warning 6334 (sizeof operator ... might yield unexpected results) around invocations of macro BOOST_IOSTREAMS_BOOL_TRAIT_DEF (issue #1618)

svn path=/trunk/boost/iostreams/; revision=45788
added static assert to fix issue #1580

svn path=/trunk/boost/iostreams/; revision=45790
added grep_filter and tests (issue #1627); line_filter needed modification to be usable as a base for grep_filter; the commented out tests for grep_filter::count() are incorrect, because they query the original filter rather than the copy used for i/o; I have verified independently that count() works, and will fix the test later

svn path=/trunk/boost/iostreams/; revision=45833
added partial specializations of category_of and mode_of for reference wrappers; allows ref(c) to be treated as a filter or device if c is a filter or device

svn path=/trunk/boost/iostreams/; revision=45837
suppressed 'condition is always true' warning

svn path=/trunk/boost/iostreams/; revision=45838
removed spurious bitwise complement in close_impl()

svn path=/trunk/boost/iostreams/; revision=45839
fixed tests for grep_filter::count() by passing a reference wrapper instead of a copy to io::compose

moved code suppressing VC warning 6334 into disable_warnings.hpp

svn path=/trunk/boost/iostreams/; revision=45843
added documentation for grep filter; fixed broken links
