Saving with a non-GPX extension does strange things

[Maarten]

While testing I came across this strange behaviour: when you save to a GPX file with a non-gpx extension, everything after the last . (dot) gets removed and then .gpx is added.
So if you do save as, save as gpx (1.0 or 1.1), use filename "test-2.19-1", it will get saved as "test-2.gpx". I would have expected "test-2.19-1.gpx".
If you enter "test-2.19-1.gpx" as filename, it will get saved as "test-2.19-1.gpx".

Dear Maarten,

that behaviour is intended to avoid that users save files and omit the extension.

So if you do save as, save as gpx (1.0 or 1.1), use filename "test-2.19-1", it will get saved as "test-2.gpx". I would have expected "test-2.19-1.gpx".

That's a side effect that could only be omitted if the check for a valid extension could determine more precisely what to cut off.
