[PATCH v4 0/2] dir: traverse into repository (resending)

[Goss Geppert <gg.oss@outlook.com>]

From: Goss Geppert <ggossdev@gmail.com>

Attempt #2 to send this.  It seems sending patch v4 2/2 resulted in an
error with the outgoing server.

Original message below:

This latest version of the patch series contains relatively minor
modifications relative to the previous version.  Let me know if there
is anything else I need to do.

Changes compared to v3:
* remove the commit that caches the gitdir's realpath as this was deemed
  a premature optimization given the amount of code churn
* use git option `-C` in some of the testcases to avoid creating a
  subshell
