show symlink destination

[wedens]

Closes #196.

Shows symlink destination at the bottom, at the right of permissions/size/time.

If it's a symlink to a symlink, it'll resolve only the first one, which I think makes sense.

I've also tried adding "target" option to info, but fairly long info strings are not being displayed at all. Even when there is a lot of space.

PS: this is my first ever code in Go 🙂

@wedens Thank you very much for the patch. This has been missing for quite a while and I'm glad it is finally getting implemented.

I have tried the patch and it seems to be working great. A minor nitpick in the code is that you seem to ignore the error returned by os.Readlink which I usually try to avoid. Do you know how does os.Readlink fail? If it's a rare error maybe just add an early return with the error (e.g. if err != nil { return files, err }) so at least it is logged. Does that sound ok?

It seems to fail on invalid path or if it's not a symlink. Those conditions are already checked before os.Readlink call.

If it's a rare error maybe just add an early return with the error (e.g. if err != nil { return files, err }) so at least it is logged. Does that sound ok?

I've added those changes. I'm not a Go developer, so I wasn't sure what's the best practice for unlikely errors ;)

@wedens Seems good to me, thanks again.
