SUMMARY

I have configured "Remove trailing spaces" to "Never" in the Kate configuration.

Yet, if I open a file with existing trailing spaces, edit a bit, then save it, then trailing spaces are automatically removed by Kate. I have tried with a C++ file and a regular text file, to make sure this wasn't specific to a file type.

I have also tried setting "Remove trailing spaces" to "On modified lines" and got the same result.

STEPS TO REPRODUCE
1. Set "Remove trailing spaces" to "Never" in the Kate configuration dialog; press "Apply" and close
2. Open a file with existing trailing spaces
3. Edit the file in some other places
4. Save the file

OBSERVED RESULT

Trailing spaces have been removed on saving, despite Kate being told not to do so.

EXPECTED RESULT

Trailing spaces should have been left intact.
