vsc hold last commit message

1. just use Alt +Up/Down arrow key

2. or use git hooks

$>
    echo "My fancy commit message" > .git/last-commit-msg.txt
    git config --local commit.template .git/last-commit-msg.txt


#!/bin/sh
#
# .git/hooks/post-commit
printf "`git log -1 --pretty=%s`" > .git/last-commit-msg.txt


$>
    chmod +x .git/hooks/post-commit
