[Message part 1 (text/plain, inline)]

My point is that there is a bug in some cases. I agree that in other cases, 
make-symbolic-link does work.

With the proposed changes a user can create a local symlink to an any string 
supported by the operating system. This change increases users' capabilities, 
compared to what they can do now. This change does not take away any capabilities.

Good suggestion, also made by others. Revised patch attached.
