text formatting helpers work as expected

Code
  format_text(c("A very long First", "Some similar long Second", "Shorter Third",
    "More or less long Fourth", "And finally the Last"), width = 20)
Output
  [1] "A very long First,\nSome similar long\nSecond, Shorter\nThird, More or less\nlong Fourth and And\nfinally the Last\n"

Code
  format_text(c("A very long First", "Some similar long Second", "Shorter Third",
    "More or less long Fourth", "And finally the Last"), last = " or ", enclose = "`",
  width = 20)
Output
  [1] "`A very long\nFirst`, `Some\nsimilar long\nSecond`, `Shorter\nThird`, `More or\nless long Fourth`\nor `And finally the\nLast`\n"

text formatters respect `width` argument

Code
  long_text <- strrep("abc ", 100)
  cat(format_text(long_text, width = 50))
Output
   abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc
Code
  cat(format_text(long_text, width = 80))
Output
   abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc
  abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc
Code
  withr::with_options(list(width = 50), code = {
    cat(format_text(long_text))
  })
Output
