    Fix emacs error when M-.-ing to nonexistent file
    
    When the Lisp reports a source location is in a file that doesn't
    exist, and also gives the :align t hint, slime-location-offset
    will try to (slime-forward-sexp) (beginning-of-sexp) in a new
    empty buffer. This causes a pretty inscrutable
    "Wrong type argument: characterp, nil" error from emacs. This
    problem may also occur if the source file does not have sexp
    syntax, but I haven't tried that myself.
    
    The change just silently ignores any errors from the sexp motion.
    It might be better to have slime report that the file isn't real
    and not do any motion to begin with.
