Enhancement for file-attributes

[Eli Zaretskii]

Would it be a good idea to enhance file-attributes by adding one more
optional argument to it, which, when non-nil, will cause Emacs call
'stat', not 'lstat', on the argument file name?  This should avoid the
need to call file-chase-links when all we want is to get the
attributes of the file pointed to by the symlink.
