Subject: [PATCH 5/6] Add plan9/wrap.c
Date: Sat, 03 Aug 2019 16:52:12 -0700 (PDT)	[thread overview]
Message-ID: <d00bbdce0d5104f1793b7fa0dce14f678e9fb331.1564876327.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.305.git.gitgitgadget@gmail.com>

From: lufia <lufia@lufia.org>

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.
