I would write a small shell script that uses the find command to
generate the file names, and use emacs' command line options to do the
processing:

#!/bin/sh

find . -type f -name "*.ext" -print |
while IFS= read -r file; do
  emacs --batch "$file" \
        --eval "(vc-checkout buffer-file-name)" \
        --eval "(indent-region (point-min) (point-max) nil)" \
        --funcall save-buffer
done
