Summary
curl removes wrong file on error
Details

curl might remove the wrong file when --no-clobber is used together with --remove-on-error.

The --remove-on-error option tells curl to remove the output file when it returns an error, and not leave a partial file behind. The --no-clobber option prevents curl from overwriting a file if it already exists, and instead appends a number to the name to create a new unused filename.

If curl adds a number to not "clobber" the output and an error occurs during transfer, the remove on error logic would remove the original filename without the added number.
