I created a pull request to add string import dependencies by replacing 
the protection attribute with "string": 
https://github.com/D-Programming-Language/dmd/pull/2835

Visual D just ignores the new lines, but newer versions can support it.

I don't think the other output of -deps (without filename) is needed for 
make-like build tools.
