FWIW, OpenBSD test(1) says--

     --LL _f_i_l_e
             True if _f_i_l_e exists and is a symbolic link.  This operator is for
             compatibility purposes.  Do not rely on its existence; use --hh
             instead.

Note that last part. Is "-L" actually more standard? (Even on other
*cough* Unices, me's always used "-h").

There's also stat(1), but that appears to be even less standard than
readlink(1).
