Quote from Zalewa
Newline consistency across the whole project is not needed. It's only needed to have newline consistency in a file. If there are inconsistent lines in some file then this file has problems and should be fixed.

There's tools/normalize_nl.py in the Doomseeker repo that can scour a whole subdirectory tree and alter all files within it to have the dominating newline style in each file be the consistent one in that single file.

Files that are 3rd party should not be modified even if they have inconsistent newlines.

Actually, one line is not consistent in src/core/datapaths.h.
