Then you could amuse yourself further by looking at the existing
line lengths of .rst files.

$ git ls-files -- '*.rst' | \
  xargs cat | \
  awk '{print length($0);}' | \
  sort -n | \
  uniq -c | \
  tail -20
      2 226
      1 230
      1 233
      1 234
     48 246
      1 253
      2 257
      1 263
      1 270

Other than testing whether or not an SPDX license line exists,
checkpatch doesn't inspect .rst files.

There are better tools for that.
