mdocml: Three portability improvements by millert@: * Use "\\ " not

[schwarze]

Log Message:
-----------
Three portability improvements by millert@:
* Use "\\ " not "\\~" as the non-breaking space as historic nroff
doesn't support the latter.
* The '-' before the flags needs to be quoted to prevent nroff
from putting a line break between the '-' and the flag character.
* Disable hyphenation and, for nroff, disable justification which is
consistent with how mdoc behaves (and produces more readable manuals).

(OpenBSD rev. 1.39, 1.40 and 1.41)
