It does seem  to be a good idea but it would leave the 'prepare-commit-
msg' hook with no scripts that could be used by just activating it.
That's why I thought of adding a script that removes the "Please enter
your.." message from the comments if it exists. A typical patch will
follow.

Enabling the "prepare-commit-msg" hook with the patch that follows
would do have following result,

Before,

    # Please enter the commit message for your changes. Lines starting
    # with '#' will be ignored, and an empty message aborts the commit.
    # On branch hook-test-merge
    # Changes to be committed:
    #    	    new file:   commit-msg
    #

After,


    # On branch hook-test-merge
    # Changes to be committed:
    #    	    new file:   commit-msg
    #


A typical consequence for "git commit --amend" would be,

Before,

    Test commit

    # Please enter the commit message for your changes. Lines starting
    # with '#' will be ignored, and an empty message aborts the commit.

After,
