Subject: [PATCH 5/6] Add plan9/wrap.c

From: "lufia via GitGitGadget" <[email-masked]>

From: lufia <[email-masked]>

Plan 9 has bind(1) instead of ln(1), but bind isn't persisted to the disk.
However it isn't efficient to copy git to git- subcommands such as git-add.
Therefore Plan 9 needs wrap.c to switch behavior by executable name.
