Easier way to modify with changeColumn?

[joshbmarshall]

Hi, when changing a column, e.g. a new comment, default value or nullable yes/no we currently have to set all the attributes of the column.

Is there a way that we can just specify the attributes that change? Either through another function call e.g. changeColumnNull() or changeColumnComment() or by adding a flag to changeColumn() to indicate to start with the current column attributes and set only the options that have changed?

Is this a duplicate of #1221 ?

Very close, apologies the issue search did not find that one for me. I will look into using getColumn() as a workaround.

It would also be nice to not have to specify the field type. e.g. working with some pre-existing systems that have uncommon column types.

This is open as cakephp/migrations#941 on migrations.
Someone could backport it if the solution works.
