|
|
# git rev-parse --show-cdup printed a path relative to

# clone-repo/subdir/, not subdir-link/. Git rev-parse --show-cdup
|
|
# used the correct .git, but when the git pull shell script did
|
|
# "cd $(git rev-parse --show-cdup)", it ended up in the wrong
|
|
# directory. A POSIX shell's "cd" works a little differently
|
|
# than chdir() in C; "cd -P" is much closer to chdir().
