37 # From subdir-link, pulling should work as it does from
38 # clone-repo/subdir/.
40 # Instead, the error pull gave was:
42 # fatal: 'origin': unable to chdir or not a git archive
43 # fatal: The remote end hung up unexpectedly
45 # because git would find the .git/config for the "trash directory"
46 # repo, not for the clone-repo repo. The "trash directory" repo
47 # had no entry for origin. Git found the wrong .git because
48 # git rev-parse --show-cdup printed a path relative to
49 # clone-repo/subdir/, not subdir-link/. Git rev-parse --show-cdup
50 # used the correct .git, but when the git pull shell script did
51 # "cd `git rev-parse --show-cdup`", it ended up in the wrong
52 # directory. A POSIX shell's "cd" works a little differently
53 # than chdir() in C; "cd -P" is much closer to chdir().
