Bug 17170 – ddoc shows parameters that are not used in function

https://dlang.org/library/std/process/pipe_process.html shows shellPath The path to the shell to use to run the specified program. By default this is nativeShell. but shellPath isn't used in pipeProcess: ProcessPipes pipeProcess( const(char[][]) args, Redirect redirect = cast(Redirect)7, const(string[string]) env = cast(const(string[string]))null, Config config = cast(Config)0, const(char[]) workDir = null ) @safe; ProcessPipes pipeProcess( const(char[]) program, Redirect redirect = cast(Redirect)7, const(string[string]) env = cast(const(string[string]))null, Config config = cast(Config)0, const(char[]) workDir = null ) @safe; https://issues.dlang.org/show_bug.cgi?id=13270 is related but different

ddox is missing the 3rd overload, see ddoc: https://dlang.org/phobos/std_process.html#.pipeProcess This needs to be filed for ddox.
