We have the same issue, it created issues on our CI since we pull freertos as a dependency.

Same here. Changing a line in a file results in whole file being changed, see for example #249

Yikes yes it is very inconvenient. Deleted the file and deferring line-terminator unification to our code beautifier.
Thanks All for highlighting this. Please re-open as needed.
