Comment 20 for bug 170225

> I'm thinking that we want to do this in C++, not C.

I reused the same syntax as the original code. And since it was not part of the recent C++ification, it still needs refactoring.

Could you please give some details? Do you mean the patch could be made differently (and more efficiently) or the whole code?

Would you mind if I commit the current patch? As far as I can tell, it doesn't add any regression compared to how relative links worked with 0.46 and doesn't break anything else in Inkscape. If it's a matter of C++ification, I guess that's something we could do after the bug is fixed. Except of course if there are horrors in the patch...
