Question about 'error' type exit codes in the 'warning' exit code range

[chocmake]

In the v1.x docs it lists exit codes for when the BORG_EXIT_CODES environment var is set to modern which enables a range of more specific error and warning codes.

The docs group code 1 and codes 100 and onward as 'warning' type ranges, while 2 to 99 as 'error' type range, however some of the warning messages are described as errors, including 102 (BackupError) and 106 (BackupIOError).

What I was wondering is what makes them warnings vs being in the errors range? As it reads like some are non-ignorable and/or critical issues, while others seem more benign (eg: 103, which is just a skipped file), so trying to determine if I should be cherry-picking which errors to consider critical for my own custom parsing.

For borg exit codes, the difference is like:

• an error is something fatal and borg immediately terminates with an rc in the error range
• a warning is something notable, but borg usually will continue (e.g. borg create can not read one file, will emit a warning, but will continue backing up other files) and then, after it has processed the last file, terminate with an rc in the warning range.

So, for that one file, there was an error, but overall it resulted only in a warning msg and warning rc.
