(no subject)

I'm not sure if this is a bug.

To reproduce:
1. Set the contents of .git/hooks/prepare-commit-msg to this:
```
#!/bin/sh

COMMIT_MSG_FILE=$1

echo "Initial Commit." > "$COMMIT_MSG_FILE" echo "" >> "$COMMIT_MSG_FILE" echo "# Some random comment." >> "$COMMIT_MSG_FILE" ``` Notice the comment being added to the file.

2. Append a commit with the --no-edit flag.
`git commit --amend --no-edit`

The comment ("Some random comment" in this case) is included in the final commit message, but it shouldn't right?

If I don't pass the flag and just save the commit without changing anything, the comment isn't included. Shouldn't this be the case with the --no-edit flag too?
