For compatibility with the man(1) implementations of the man-1.6
and man-db packages, print the manpath if the -w option is given without a following name argument. This quirk has been in man-1.6 since at least man-1.5e (1998) and in man-db since 2012. Using this feature in portable software is a dubious idea because the internal organization of manual page directories varies in about a dozen respects among operating systems, so even if you get the answer, there is no portable way to use it for looking up anything inside. However, Matej Cepl <mcepl at suse dot cz> made me aware that some software, for example the manual viewing functionality in the newest editors/neovim code, unwisely relies on this feature anyway. No objections were raised when this patch was shown on tech@.
