This patch revisits the tooltips of bonus attacks. It replaces "x" (X) with "×" (multiplication symbol), "vs." with "vs" (abbreviations only end with a dot if they are shortenings (e.g. etc.), but not if they are contractions containing the first and last letter of the word (Dr, Mrs, vs), initialism (GB, MP, PM, UK, UN), or acronyms (Aids, laser)), and removes unnecessary extra words.
There is a patch that would automatically generate these tooltips (D1707), but its current status is unclear.
