during the preprocessing phase, an unescaped newline should close a string literal, for example
#define foo FOO
when passed through "pcc -E" should substitute the second foo, producing
this affects distributions such as X11 which uses the C preprocessor to substitute keywords in manpages which have .\" as comment marker.. cpp enters string literal mode at the first occurrence and never exits, causing no substitutions to be done.
(Xorg seem to be moving away from cpp for this, but there are still usages)
incidentally, as the file is ended in string literal mode, there is a spurious 0xff character output at the end
