Inconsistency in use of "--bare" between init & clone

I've been getting ready to support my organization in a change-over to
git from cvs, and I've found a strange issue when creating bare
repositories.  The placement of the "--bare" option changes:

git --bare clone <url>  ==  "--bare" is silently ignored
git --bare init  ==  Creates an empty bare repo

git clone --bare  ==  Clones the url into a new bare repo
git init --bare  ==  Error:
        usage: git-init [-q | --quiet]
[--template=<template-directory>] [--shared]

I assume there a reason for the lack of symmetry, but I don't understand it.

Thanks,
Joe
