with GNU groff – add some special handling to the BSD mdoc macros for it so that the manual pages look good in both utf8 and ps (PDF) mode; also fix in mksh wrong display of ` (groff: ‘), ' (groff: ’), \' (groff: ´), \- (groff: U+2212 −), the en dash (nroff doesn’t have it, use the em dash there ONLY), and ~ and ^ (groff: placed atop and size-reduced, for use as diacritics, in manual pages bad since these are control characters there) → PDF manpage now has ‘’ “” and good-looking hyphens and mini and ~ and ^ → utf8 manpage now has ‘’ “”, good-looking hyphens, cut’n’pasteable mini → nroff manpage still has '' "" instead of ugly `' ``'' or even `´ → Debian lintian won’t complain any longer
