That happens in `file-truename'. Every path component must be checked
for being a symlink. During this check, other primitive file name
operations are called, which call then `expand-file-name'.

In Tramp 2.1, several file name operations cache their result;
therefore much less calls are necessary.

Best regards, Michael.
