PullMark 0.21.0

• Content width — choose how far text may stretch before it wraps:
  Standard (the classic reading measure, still the default), Wide
  (longer lines, more on screen, still capped), or Full Width (the
  document gets the whole window — made for full screen). Pick in
  Settings → Themes with illustrated previews, or switch mid-read from
  View → Content Width; changes apply live to every open document and
  keep your place. Plays with every theme, the blame gutter, diffs, and
  zoom. Requested by a full-screen reader tired of the dead space.
