Missing extension when using -o to convert filenames with periods

[zecanard]

Simple steps to reproduce:

1. Take a screenshot. It will be named something like Screenshot 2026-03-11 at 19.57.25.png
2. Run

   Code: Select all

   nconvert -o ~/Desktop/% -out jpeg "Screenshot 2026-03-11 at 19.57.25.png"

The output file is ~/Desktop/Screenshot 2026-03-11 at 19.57.25 with no extension, despite not having specified -no_auto_ext.

Omitting -o produces an output with the correct extension. Using -o on a filename that does not contain periods also appends the correct extension.

I tested this under macOS v7.232.
