HELPNEEDED: Do not resolve symlinks to realpath

[mih]

I believe this creates more headache than it helps. But it seems like an
assumption that is baked in deep. This is to start figuring out
how deep.

[coveralls]

Coverage decreased (-0.02%) to 86.587% when pulling 5dbfaba on mih:rf-pathresolution into 64730e6 on datalad:master.

Current coverage is 86.76% (diff: 100%)

Merging #745 into master will increase coverage by 0.15%
