what about the following?

import std.algorithm, std.array, std.regex;
import std.stdio, std.file;
void main()
{
   auto exclude = regex(r"\.git", "g");
   dirEntries("/path/GIT", SpanMode.breadth)
     .filter!(a => match(a.name, exclude).empty)
     .writeln();
}

I think if you go breadth first, you can filter out the unwanted 
directories before it delves into them
