Details:

This is effectively the same problem as bug 11148 (fixed long ago) but now in
the fts version of the code.

$ ln -s a b
$ ln -s b a
$ find --version
GNU find version 4.3.3
Built using GNU gnulib version 2007-04-14
Features enabled: D_TYPE O_NOFOLLOW(enabled) LEAF_OPTIMISATION FTS(FTS_CWDFD)
CBO(level=0) 
$ find -L a
a

It should report an error when it gets ELOOP, as with the non-fts version of
find:

$ find-4.2.28 -L a     
find-4.2.28: a: Too many levels of symbolic links

The original fts code also did not have the problem.  It has come in since
the last time I tried the fts version (from CVS in August 2005).
