If you add an

  echo "$file"

inside the while loop, what do you see?

I deliberately set the .git directory to be ignored (using @) to avoid tons of repeating when the index.lock file is repeatedly recreated. Maybe that's what's going on here.

index.lock CREATE index.lock DELETE

alternating very fast.

Agh, it's my fault.

I must have fumbled a key after pasting, as there was a dot missing; @/.git should read @./.git.

I'll add a note to the ancestor comment if I still can. Thanks and sorry!
