Subject: clone: run post-checkout hook when checking out
X-Git-Tag: v1.6.3-rc0~74^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=dfa7a6c579d75037b9dd5c3654a36d31c60f203c;p=git.git

clone: run post-checkout hook when checking out

The mental model for clone is that the branch is "checked
out" (and it even says this in Documentation/git-clone.txt:
"...creates and checks out an initial branch"). Therefore it
is reasonable for users to expect that any post-checkout
hook would be run.
