Module: packages                      Tag: HEAD
---- Log message:
- check if less would parse escape sequences as colors, either by
  LESS environment variable having -?[rR] (note: doesn't have to be separate
	word, there might be false positive test results), or
  less itself having -[rR] switch (note2: only before first non-option
	argument, so some false positives possible too)
  Skip highlight(ing) when it wouldn't interpret them.
