My recent fix for the load/save fgfs.sav feature was a bit too ambitious.
While aliases lead to abortion before, I tried to copy them properly,
although this wasn't a requirement. Unfortunately, this seems to have
worked for absolute aliases only, not for relative ones, and hence broke
several panel instruments. The attached patch backs most of the previous
patch out again, and goes a simpler route: just ignore aliases.
