      So, it's a side-effect. It'd be better if there were a side-effect-free
      version of the function. Plus the function combines two separate, but
      related, tasks pertaining to the misspelled word under the cursor (if it
      exists):

      1. Move the cursor to the start of the word
      2. Return information about the misspelling (the word and the type)

      It'd be preferable if the function returned information about the
      misspelled word, but that the information would also include its
      location. Then setpos() could be used for functionality #1.

      The version I posted (based on Ingo Karkat's SpellCheck plugin) saved
      the view, not just the cursor position. By only saving the cursor
      position, the function that moves the cursor around might also alter
      folds or the viewport (for example).

      My point in calling it unfortunate wasn't to say that it's impossible
      (or even that hard) to workaround. It just would have been nicer to
      find an API similar to :synID (which takes a (line,col)-position as
      input).
