llvm dev - Sep 2020 - I've gone and broken the build

Now I think I really have broken the build. The file
llvm/test/TableGen/BitsInit.td ended up with an occurrence of '..'
rather than '...'. But when I look at the commit I see the line with
'...'. I'm not yet too clever with git. Could someone give me a
hand?
