Attached are tweaked endings for words like "wolf" to include contracted
endings, but they are being ignored. This makes for a minor inconsistency:

  wolfing -- no ligature
  wolfish -- no ligature
  wolfin -- no ligature (incorrect spelling, though)
  wolfin' -- ligature

Any ideas? I tried adding various -in suffixes without luck:

            suffixes = [[
                in,
                in',
                in’,
                ing
            ]],

See https://wiki.contextgarden.net/Ligatures#Word_suppression for an
example usage.

Thank you!
