[PATCH 0/4] .gitignore, reinclude rules, take 2

Take one was bad and reverted in commit 8c72236. Take two provides a more complete solution to the pair of rules

  exclude/this
  !exclude/this/except/this

3/4 should do a better job at stopping regressions in take 1. 4/4 provides the solution. I think I have tested (and wrote tests) for all the cases I can imagine.

  dir.c: fix match_pathname()
  dir.c: support tracing exclude
  dir.c: support marking some patterns already matched
  dir.c: don't exclude whole dir prematurely
