Protect literals in a (very long) paragraph tag from hyphenation by
using hypenation control escape sequences, instead of `nh` and `hy`
requests. The latter approach is incorrect for use with groff(1) since
'.hy' does not restore the previous hyphenation mode but sets it to 1,
which is not appropriate for the English-language hyphenation patterns
groff uses. (Also, AT&T man(7) used a hyphenation mode of 14.)
Also wrap long input line with \newline escape sequence.
