Description Maverick 2020-10-15 16:07:48 UTC 
SUMMARY
When saving file after merge, the permissions of the file might change. This can easily result in a broken system when used to merge files in /etc under su, like when managing .pacnew in Arch Linux and is therefore a severe problem.

STEPS TO REPRODUCE
1. Touch a file test.txt and change group and others permissions in some way
2. Compare test.txt with another file, apply a difference and save
3. Check permissions of test.txt. 

OBSERVED RESULT
test.txt permissions always end up "-rw-------", no matter what they were set to in 1. Note, that those are also not the default permissions as were after initial touch.

EXPECTED RESULT
Permissions should be identical to in 1.
