The normalized path of the root as specified by the search criteria,
with the additional path components appended.
Throws an error if no root is found.
Details
This function operates on the notion of relative paths.
The ... argument is expected to contain a path relative to the root.
If the first path component passed to ... is already an absolute path,
the criterion and path arguments are ignored,
and ... is forwarded to file.path().
