Oh lord, it gets worse ...

$ cd a-repo
$ git rev-parse --is-inside-work-tree; git rev-parse --is-inside-git-dir
true
false
$ cd .git
$ git rev-parse --is-inside-work-tree; git rev-parse --is-inside-git-dir
false
true
$ export GIT_WORK_TREE="$(git rev-parse --show-toplevel)"   # !!!
$ git rev-parse --is-inside-work-tree; git rev-parse --is-inside-git-dir
true
false
$ # !!?!?

So, basically, if `$GIT_WORK_TREE` is set at all, it appears that the
`rev-parse --is-inside...` flags don't function reliably at all.
