This is yet another patch from Git for Windows. Changes since v3:
* Adjusted the commit message to reflect that this is no longer only about the hooks directory. * Added a code comment to indicate how the list of keys was determined that are used for the gitdir priming. * The gitdir cache is now re-primed upon F5. Changes since v2: * The paths returned by git rev-parse --git-path are now cached, and the cache is primed with the most common paths. Changes since v1: * Rather than a fine-grained override of gitdir just for the hooks path, we now spawn git rev-parse --git-path [...] every time gitdir is called with arguments. This makes the code safer, although at the cost of potentially many spawned processes.
