This is go-yaml/yaml#1004.

This bug is in a dependency of chezmoi and cannot be fixed in chezmoi itself. chezmoi's dependencies are regularly updated and so when this is fixed in the dependency chezmoi will get the fix soon after. So, I will close this as won't fix.

Note, however, that if you have a template variable for newlines you should probably be using a template line ending directive instead, i.e. your templates should contain

chezmoi:template:line-endings=native
