That too is probably wanted?  If I attach foo that's a symlink to bar by
naming foo then I want foo to continue into the MIME headers, not bar?

-H and -L never change the name shown for this reference of the given
inode, they only change whether stat(2) or lstat(2) is used.  Also, -H
does a -L but only for explicitly named on the command line arguments.
This is working as I'd expect:

    $ ls -l
    total 0
    -rw-r--r-- 1 ralph ralph 0 2012-09-15 18:49 a
    lrwxrwxrwx 1 ralph ralph 1 2012-09-15 18:49 b -> a
    $ ls -lL
    total 0
    -rw-r--r-- 1 ralph ralph 0 2012-09-15 18:49 a
    -rw-r--r-- 1 ralph ralph 0 2012-09-15 18:49 b
    $ ls -lH
    total 0
    -rw-r--r-- 1 ralph ralph 0 2012-09-15 18:49 a
    lrwxrwxrwx 1 ralph ralph 1 2012-09-15 18:49 b -> a
    $ ls -lH a b
    -rw-r--r-- 1 ralph ralph 0 2012-09-15 18:49 a
    -rw-r--r-- 1 ralph ralph 0 2012-09-15 18:49 b
    $

If the `points to' name is wanted then readlink(1) is used.

Cheers, Ralph.
