[PATCH v3 0/4] dir: more fill_directory() fixes

This is a follow up to en/fill-directory-fixes, and has grown from 1 patch
in v1 to 4 patches in v2, 3 of which are submissions by others to the git
list that I've just combined into one series since they are all about
fill_directory().

The first two patches may make sense to include in maint at some point,
though Stolee isn't that concerned about this regression[5][6].

 * The first patch is Kevin and Stolee's testcase showing a regression in
   "git clean -f "[1]
 * The second patch is a "simple" fix for that testcase with a pretty long
   (and slightly embarrassing though entertaining) backstory.
 * The third patch was from v1, and is a small tweak made by me to a patch
   proposed by Peff[2] (signoff from [3]) to avoid needing to create a
   dirent.
 * The fourth patch was a follow-up from Peff in response to V1 fixing a
   code comment[4].
