Doug Davis d25588047e Align 'docker commit' docs with the code
It was missing some variants and 'maintainer' isn't actually supported.
Also sorted the list of allowed cmds in the code just to make it easier
to diff with the docs.

# NAME
docker-commit - Create a new image from a container's changes
# SYNOPSIS
**docker commit**
[**-a**|**--author**[=*AUTHOR*]]
[**--help**]
[**-c**|**--change**[= []**]]
[**-m**|**--message**[=*MESSAGE*]]
[**-p**|**--pause**[=*true*]]
CONTAINER [REPOSITORY[:TAG]]
# DESCRIPTION
Create a new image from an existing container specified by name or
container ID. The new image will contain the contents of the
container filesystem, *excluding* any data volumes.
While the `docker commit` command is a convenient way of extending an
existing image, you should prefer the use of a Dockerfile and `docker
build` for generating images that you intend to share with other
people.
# OPTIONS
**-a**, **--author**=""
Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
**-c** , **--change**=[]
Apply specified Dockerfile instructions while committing the image
Supported Dockerfile instructions: `CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`LABEL`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR`
**--help**
Print usage statement
**-m**, **--message**=""
Commit message
**-p**, **--pause**=*true*|*false*
Pause container during commit. The default is *true*.
# EXAMPLES
## Creating a new image from an existing container
An existing Fedora based container has had Apache installed while running
in interactive mode with the bash shell. Apache is also running. To
create a new image run `docker ps` to find the container's ID and then run:
# docker commit -m="Added Apache to Fedora base image" \
-a="A D Ministrator" 98bd7fc99854 fedora/fedora_httpd:20
## Apply specified Dockerfile instructions while committing the image
If an existing container was created without the DEBUG environment
variable set to "true", you can create a new image based on that
container by first getting the container's ID with `docker ps` and
then running:
# docker commit -c="ENV DEBUG true" 98bd7fc99854 debug-image
