Comment 21 for bug 214366

this patch needs work before it can get checked in, as Seth pointed out. Since
it was written, the string classes have changed quite a bit, so I think a lot of
the copying is unneeded, and you can use the Equals method to compare
nsXPIDLStrings, so there's no need for the auto strings. To format messages with
unicode strings, you just use %S instead of %s in the format string like so:
+4023=The Trash already contained a folder named %S. The folder which you just
deleted can be found in the Trash under the new name %S.

Also,
               newFolderNameUnderTrash.AppendInt(i,10);
should just be newFolderNameUnderTrash.AppendInt(i); since 10 is the default.
