Replying to [comment:5 Pete]:
> OK -- glad that you think it not quite right, too. I don't see it as
the application's job to fix it, though. Shouldn't this be the
FilePanel's responsibility? Having the alert give a choice of replacing
either the link itself or the file it references might be the best route.
No, it's the application. All the file panel does is select a file, it's
in no way responsible for the subsequent modifications, and it does in
fact give back a reference to the symbolic link. However, under normal
circumstances, when one opens a file, the filesystem API calls deal with
following the link and opening its target implicitly, as this allows apps
to transparently work with symlinks without any extra work. In the case of
an overwrite, what one normally does is open the file with a truncate
flag, and then start writing the new contents. However, if the target is a
symlink, this obviously doesn't quite result in the desired behavior, so
the app does have to be smart enough to detect that situation when being
asked to save/overwrite.
