[erlang-questions] symlink error (I think)

[Bengt Kleberg]

Greetings,

This is a case of "read all of the documentation to understand a part of
it". For read_link_info/1-2 it says that it is different from
read_file_info/1-2 because read_link_info/1-2 can get "the type field of
the record will be set to symlink". 

If read_file_info/1-2 could have symlink then there would be no
difference.

It would definitely be better if read_file_info/1-2 also mentioned this.
