Thanks for your detailed explanation. Yes, "git push" and "git pull"
both work fine out of the box. That is the good thing. But,
$ grep git git-pull.sh
. git-sh-setup
orig_head=$(git-rev-parse --verify HEAD) || die "Pulling into a black hole?"
git-fetch --update-head-ok "$@" || exit 1
curr_head=$(git-rev-parse --verify HEAD)
git-read-tree -u -m "$orig_head" "$curr_head" ||
var=`git repo-config --get pull.octopus`
var=`git repo-config --get pull.twohead`
merge_name=$(git-fmt-merge-msg <"$GIT_DIR/FETCH_HEAD")
git-merge $no_summary $no_commit $strategy_args "$merge_name" HEAD $merge_head
We have "git-read-tree" and "git repo-config" at the same time. Are
there any rules saying which form should be preferred? How about pick
one form and stick to it?
If we uniformly call git helper programs/scripts with "git helper"
style, would git(1) append two paths to PATH everytime it is being
invoked? For example, "git pull" -> "git repo-config" would prepend
~/opt/bin four times to PATH. This wouldn't be very effecient.
