cell vector (bracket) support?

[BaconPancakes]

Is there an analogous rule for formatting multi-line cell vectors, similar to the matrix formatting? Seems that indents are just removed in this case.

I didn't even know that cell arrays even exists ;)
I added the requested feature in the new version.
However, since cell arrays may be rather complicated, it doesn't yet work for all scenarios.
For now, only one layer of cells is allowed. So e.g.

C={1
    [2 3]
    {4 5 6}}

will work. If you try to also break the inner cell into multiple lines like

C={1
    [2 3]
    {4 
    5 
    6}}

, the formatter will fail. If this becomes a problem (for a reasonable amount of people ;)), I'm going to try fixing it.
