5118,replace_extension doesn't work as specified in documentation,bitfield.alex@…,Beman Dawes,"1. From Reference (see http://www.boost.org/doc/libs/1_45_0/libs/filesystem/v3/doc/reference.html#path-replace_extension):

{{{
path& replace_extension(const path& new_extension = path());

Postcondition: extension() == replacement, 
where replacement is new_extension 
  if new_extension.empty() || new_extension[0] == the dot character, 
otherwise replacement is the dot character followed by new_extension.

Returns: *this
}}}
Testing this behavior
{{{
path ph(""foo.txt"");
std::cout << ph.replace_extension(""exe"");
}}}
Output:
{{{
foo
}}}
Eather change the Reference or fix it in code.

2. Current implementation doesn't allow to work with complex extentions.

{{{
path ph(""foo.txt"");
std::cout << ph.replace_extention("".tar.bz2"");
}}}
Output:
{{{
foo.bz2
}}}

3. There is no function to just add extension.
something like that:
{{{
path ph(""foo.txt"");
std::cout << ph.add_extension(""bz2""); 
}}}
Expected output:
{{{
foo.txt.bz2
}}}
