If there was an unmatched word 'foo', and someone wrote 'foo. bar.', wordbot would not recognize the match because it was only splitting the string on spaces, not punctuation. This treats as a word any contiguous sequence of letters, numbers (just in case) and hyphens (just in case). Signed-off-by: Alek Ratzloff <alekratz@gmail.com>
