On Mac OS X, JOSM asks twice to overwrite a file

[Zverikk]

Create a layer, "File", "Save As", choose an already existing file. The file dialog asks if you want to overwrite it. Answer "Yes".

Then JOSM asks the same question with a little clumsy dialogue. That is clearly redundant.

Is it the same behaviour with both native and Java file choosers? (see my comment in #11363)

[Zverikk]

No, Java file chooser doesn't ask to overwrite a file. So there must be a check, I guess: if the native dialog is used, assume user already answered the question.

[Don-vip]

ok thanks

In 8248/josm:

fix #11362 - do not confirm overwrite for OSX native file dialogs which already ask for it
