Everybody has git.  Everybody who edits .gitattributes can use git to 
check what they did.  Not everybody has editorconfig-related tools.  I 
tried the editorconfig-checker that you had mentioned (I tried the Go 
version, not the JavaScript one, because the former is packaged for 
Homebrew and Debian), but it was terrible and unusable.  Maybe I'm 
holding it wrong.  But I don't want users of a common tool to bear the 
burden of blindly updating files for a much-less-common tool.  This is 
how we got years of blindly updating Windows build files.  The result 
will be to that people will instead avoid updating .gitattributes.

ISTM that with a small shell script, .editorconfig could be generated 
from .gitattributes?
