fix: remove the em-dashes this release added (release review)

105 new em-dashes sat in comments, test names and one test fixture from the
foreign tmux adoption work. Replaced by hand with commas, colons or
parentheses, one reading at a time. The fixture now quotes the real refusal
text, which says "It may still be running, try again."
