Ah, this works:
GROFF_NO_SGR= LESS_TERMCAP_us="^[[3m" LESS_TERMCAP_ue="^[[23m" man ls
no matter what the value of GROFF_NO_SGR is. Which tool in the `man` 
chain interprets the latter?

Value-added of my package:
* automatic injection into the `man` pipe
* terminal-dependent enabling, after checking the terminal type
