patch for Stdio.append_path

Some docs on what it actually does with drive letters and UNC paths would be nice.

+string append_path_nt(string absolute, string ... relative) +{

• return combine_path(absolute,

•       @map(relative, lambda(string s) {
  

• 		       if(s[1..1] == ":") {
  

• 			 s = s[0..0] + s[2..];
  

• 		       }
  

• 		       return combine_path("/", s)[1..];
  

This looks wrong. Where's your test suite? ;) ^^^^^

• 		     }));
  

+}

+#ifdef __NT__ +function(string, string ... : string) append_path = append_path_nt; +#else +function(string, string ... : string) append_path = append_path_unix; +#endif

Please use a wrapper function instead:

string append_path (string absolute, string ... relative) { #ifdef __NT__ return append_path_nt (absolute, @relative); #else return append_path_unix (absolute, @relative); #endif }

It's more efficient.
