Option to avoid overwriting customized paths

[andyinabox]

It would be nice if there was a simple toggle option that avoids overwriting existing paths in the requirejs config file.

For instance: some packages are setup so that the "main" script is not what I want (say it's a minified version of the script instead of source, or it's an index.js file that only works with node.js), but grunt-bower-requirejs automatically sets that path. Even if I correct the path, every time I update my bower dependencies it gets overwritten with the wrong path.

I recognize that I could explicitly fix this with the exclude option, but a more desired behavior would be for the task to assume that if there is already a path for a certain module in the config, that it should leave it alone.

Maybe if there were a simple overwrite option that defaulted to true, but when set to false would leave existing paths?

With this configuration you would run into unexpected conflicts when paths of installed bower components change after updating a package. In this case it should be the desired behavior for this task to overwrite the path.
I would prefer the exclude option for manually changed module paths but maybe combining the overwrite option with a check for file existence could be a way to go.
