-------------------------------------+-------------------------------------
 Hi, I have read the specification of
 boost::filesystem::path::replace_extension(const path& new_extension).
 It is very helpful in most of common use but the method may be ignore
 replacement when path represents the following cases:
 - dot (.)
 - dot-dot (..)
 - root-name (C:, //myserver, \\myserver)

 The version available in boost 1.62.0 provide the following behaviour

 {{{
 Replace extension on root path: (arguable)
 ------------------------------------------

 replace_extension("/","txt") = "/.txt"
 replace_extension("C:\","txt") = "C:\.txt"

 Replace extension on special file-name
 --------------------------------------

 replace_extension(".","txt") = "..txt"
 replace_extension("..","txt") = "...txt"
 replace_extension("/foo/.","txt") = "/foo/..txt"
 replace_extension("/foo/..","txt") = "/foo/...txt"

 Replace extension on root-name
 ------------------------------

 replace_extension("C:","txt") = "C:.txt"
 replace_extension("\\myserver","txt") = "\\myserver.txt"
 }}}
