Hi,

Cdlatex environment inserted via org-cdlatex-environment-indent are pretty
bad at getting the right indention.  Consider:

    - concept :: a long description of concept |

Where | is cursor.  When I call org-cdlatex-environment-indent, I expect 

    - concept :: a long description of concept
          \begin{equation}
          |
          \end{equation}

But I get 

    - concept :: a long description of concept
    \begin{equation}
    |
    \end{equation}

This is because it determines the indention after the element is inserted
at column zero.  So the correct indention /is/ column zero but I wanted it
to be part of the description.  IOW I want Org to use the correct
indention of when the time when I call the command.

Note that I can still get an environment at column zero by issuing the
command here:

    - concept :: a long description of concept
    |

This patch just fixes this for org-cdlatex-indent-environment only, but
maybe it's more correct to fix it in org-indent-region?
