I am playing around with detached worktrees and have identified
a number of bugs in the path handling. Specifically, it seems that
while git-status and git-add/git-rm are consistent with respect to
each other, they expose different behaviour in different scenarios.
git-diff, on the other hand, seems broken with respect to worktree
handling.

Let me run you through what I did, bugs are
identified with ###BUG. Output is prefixed with #, which should make
it easier to cut-n-paste to reproduce



Note how $GIT_DIR is set for the first part of this exercise:

mkdir worktree
GIT_DIR=repo.git; export GIT_DIR
git --bare init
# Initialized empty Git repository in repo.git/
git config core.bare false
git config core.worktree ../worktree

echo This is just a file called foo > worktree/foo

git add worktree/foo
# fatal: pathspec 'worktree/foo' did not match any files
###BUG: git should be able to factor out the common path prefix

ls foo
# ls: cannot access foo: No such file or directory
git add foo      # very confusing, but works

git commit -m'initial checkin'
# Created initial commit 2f2cdf3: initial checkin
#  1 files changed, 1 insertions(+), 0 deletions(-)
#  create mode 100644 foo

git status
##  On branch master
# nothing to commit (working directory clean)

git diff
# diff --git a/foo b/foo
# deleted file mode 100644
# index 27b451e..0000000
# --- a/foo
# +++ /dev/null
# @@ -1 +0,0 @@
# -This is just a file called foo
###BUG: git-diff doesn't seem to honour worktree and thinks the file
###was deleted

git diff -- worktree/foo
###BUG: no output, even though path was given

echo Another line >> worktree/foo
git status
# # On branch master
# # Changed but not updated:
# #   (use "git add <file>..." to update what will be committed)
# #
# #       modified:   foo
# #
# no changes added to commit (use "git add" and/or "git commit -a")

git diff -- worktree/foo
###BUG: no output, even though path was given

git add foo
# diff --git a/foo b/foo
# deleted file mode 100644
# index 76404d8..0000000
# --- a/foo
# +++ /dev/null
# @@ -1,2 +0,0 @@
# -This is just a file called foo
# -Another line

git diff --cached
# diff --git a/foo b/foo
# index 27b451e..76404d8 100644
# --- a/foo
# +++ b/foo

-----------
If worktree is actually an ancestor of the Git repository *and* we
chdir() into the repository, whether GIT_DIR is set or not, things
look different again:

mv ../worktree/* ..
rmdir ../worktree
git config core.worktree ..
git status
# # On branch master
# # Changed but not updated:
# #   (use "git add <file>..." to update what will be committed)
# #
# #       modified:   ../foo
# #
# # Untracked files:
# #   (use "git add <file>..." to include in what will be committed)
# #
# #       ./
# no changes added to commit (use "git add" and/or "git commit -a")

git diff
# diff --git a/foo b/foo
# deleted file mode 100644
# index 76404d8..0000000
# --- a/foo
# +++ /dev/null
# @@ -1,2 +0,0 @@
# -This is just a file called foo
# -Another line
###BUG: again, git-diff can't find the local file

git add foo
# fatal: pathspec 'repo.git/foo' did not match any files
###BUG: inconsistent with above behaviour, but consistent with
###git-status output

git add ../foo
git commit -m'another linee'
# Created commit d016799: another linee
#  1 files changed, 1 insertions(+), 0 deletions(-)
