[I've quickly looked at the mailing list archive and didn't see this
issue reported. However I might be wrong.]
The issue is simple: `git apply` does not respect the `--work-tree`
argument when called outside the repository.
The version of Git I used is OpenSUSE's official 2.1.4 but also 2.7.4
from their repositories.
The command I used is:
git --work-tree /.../some-repo --git-dir /.../some-repo/.git apply
/.../some-patch
The current working directory is completely unrelated with the
targeted work-tree (i.e. it is not a subdirectory of the work-tree).
I confirmed the above by using `strace -f -e file -- git ...`, and
although Git picks the correct path for the target work-tree and
switches there, it then switches back to the initial working directory
(the one being invoked from). See bellow the (redacted) output of
`strace`:
