# Commit, but put the last written commit message into the editor buffer.
# For this it uses .git/COMMIT_EDITMSG but deletes all lines after and including
# the first comment of the file.
# Useful for example when the commit-msg hook fails but only slight
# modifications are needed.
# Additional arguments (for example `-n` to bypass the hooks) can be passed.
