  Looks good to me. It seems to be a significant feature that is worth a release note. Maybe check https://www.mercurial-scm.org/wiki/ReleasenotesExtension and amend the commit message to include something like:
  
    .. feature::
    
       Added `--ignore-space-at-eol` diff option to ignore whitespace differences at line endings.

Maybe remove `only` since otherwise it sounds `ignorewseol` must be used together with `ignorews`.
