Implement end-of-sentence spacing at the end of man(7) macro lines.

Improves cvs(1) pcap-filter(3) readline(3) termcap(5) cvsbug(8)
mkhybrid(8) nsd-zonec(8) in multiple places and c++filt(1) com_err(3)
nsd_conf(5) term(5) nsdc(8) in one place each.
Reduces overall groff-mandoc-differences in base by about 1.5%.

Patch from Franco Fichtner <franco at lastsummer dot de> (DragonFly).
