  Improve building ignore file lists
  
  The routines to push and pop ignore files while traversing a
  directory had some issues. In particular, setting up the initial
  list would sometimes push an ignore file before it ought to be
  applied if the starting path was a directory containing an ignore
  file. Also, the pop function was not always matching the right
  part of the path and would fail to pop ignores from the list in
  some cases.
  
  This adds some tests that exercise a particular problematic case
  and then fixes the problems that I could find related to this.
  
  At some point, I'd like to isolate this ignore rule management
  code and rewrite it, but that's a larger project and right now,
  I'll opt to just try to fix the broken behaviors.
