Revision ec445074e0ac4d6003acd21c512c43c8fdb8be86 authored by Junio C Hamano on 12 March 2014, 18:04:11 UTC, committed by Junio C Hamano on 13 March 2014, 21:22:20 UTC
The original description talked only about what it does. Instead, start it with the purpose of the command, i.e. what it is used for, and then mention what it does to achieve that goal. Clarify what <start>, <url> and <end> means in the context of the overall purpose of the command. Describe the extended syntax of <end> parameter that is used when the local branch name is different from the branch name at the repository the changes are published.

# From subdir-link, pulling should work as it does from
# clone-repo/subdir/.
#
# Instead, the error pull gave was:
#
# fatal: 'origin': unable to chdir or not a git archive
# fatal: The remote end hung up unexpectedly
#
# because git would find the .git/config for the "trash directory"
# repo, not for the clone-repo repo. The "trash directory" repo
# had no entry for origin. Git found the wrong .git because
# 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().
