Subject: [PATCH] dialog: Cocoa shouldn't crash if there's a '.' in the
filters.
So something like "index.pb" will now accept any file with a ".pb" extension,
to make macOS happy. This seems like a reasonable tradeoff.
Other minor cleanups.
Fixes #12778.
(cherry picked from commit 691cc5bb5e95b4c101d874b29dd112bced86e598)
