12665,boost::filesystem::path::replace_extension(const path& new_extension) produces inintuitive path on special directory,Guillaume Labourey <guillaume.labourey@…>,Beman Dawes,"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""
}}}
