Open Git commit editor to specific cursor location

Question

I have modified my prepare-commit-msg hook to include the branch name at the beginning of my commit message (e.g. [JCH-234] -). However, when I run git commit the cursor is located at the beginning of the editor Vim. I'm looking for a way to start the cursor at the location following my branch name.

I'm aware that it's only a few extra key strokes to move the cursor however, I believe in attention to detail and would like to implement this if possible.

IMO, this is git config thing, we shouldn't add special vim script/config for it.

You can set GIT_EDITOR variable like:

GIT_EDITOR="vim -c'startinsert|norm! ggA'"

This makes everytime you git commit, git will hook your pre-commit-msg, then open vim, put cursor at the end of the first line, in your case, after your branch name, also switch to insert mode.
