Version 1.21

- Add :NextUnlessSpellError and :NextOrSpellCheck auxiliary commands.
- Allow to pass optional [++opt] [file] arguments to the :Write... commands.
- Add dependency to ingo-library (vimscript #4433). *** You need to separately install ingo-library (vimscript #4433) version 1.001 (or higher)! ***
Version 1.30

- ENH: Show words surrounding the spell error. The number of captured occurrences is controlled by g:SpellCheck_ErrorContextNum, what gets captured by g:SpellCheck_ErrorContextPattern. Thanks to Enno Nagel for the suggestion.
- ENH: Add syntax highlighting for the misspelled word, the error context text, and occurrences of the misspelled word inside the context. Enno Nagel also suggested this.
- FIX: Quickfix mappings are gone when closing and reopening the quickfix window (:cclose | copen), because a new scratch buffer is used, but the autocmd BufRead quickfix has been cleared.
