Plan for future features:

• Don't check typo upon selecting a corrected file (e.g. test/ --> test.lua --> test.lua.txt)
• Ignore if file already has a file extension (extensible ignore_condition)
• Check for similar spellings, not just filenames with the typo as a prefix
• Search for other similar filenames in the current working directory, e.g. different level of the same filename
• Option to not suggest directories
