Thanks for extending `fromkey` to support for unlocked files. When
updating some DataLad code to make use of this, a test flagged a
difference between how links and pointer files are handled: the
necessary leading directories will be created for links but not
pointer files.

The caller can of course make sure that leading directories exist, but
I think it makes sense for the locked and unlocked variants to behave
the same here. What do you think about the patch below?
