which looks like a good idea to me.

To be honest, I don't fully understand the ramifications of this
patch, but it does appear to me that some sort of patch is needed in
this area, as the existing code appends "../" and then never uses the
result.  I don't see any bug in the proposed patch, at any rate.

Relative and absolute symlinks both have their advantages, so perhaps
there should be an option?  But personally I'd think relative should
be the default, and the above-quoted patch is the simplest way to do
