Is there a function in core R that takes 2 strings and returns TRUE if
they refer to the same file? (If either does not refer to a file, I
think it would be fine if it returned FALSE.)
Compariing inode/device numbers on Unix-like systems and the output of
normalizePath on Windows would probably do it. Comparing files on
non-native file systems can mess things up so perhaps we should not
promise much.
