Revert "Avoid IO from ":p" during detection"

Browse Source 
This change failed to account for the directory edge case, where ":p:h"
has the very nice property of giving us back the original input, due to
":p" appending a trailing slash.  Without this, we fail to detect when
editing the root of the repository.

This reverts commit 1b811b88a4.
