commit-msg hook possible bad behavior with -F <file>

[Seth Raymond <seth.c.raymond@xxxxxxxxx>]

If a commit is invoked with -F <file>, indicating that the commit
message should be read from an existing file, the the
prepare-commit-msg and commit-msg hooks do not operate on <file>. The
first argument to the hook is always <git_repo>/COMMIT_EDITMSG, rather
than <file>.

Am I wrong in this line of thinking?
