lib/parseman: recognize all troff space escapes
parsetext() recognizes escapes for \& zero-width space, and \| narrow
space (1/6 em-space in troff). Recognize also \^ - half-narrow space
(1/12 em) and ignore it (found e.g. in dd(1)), and \0 - digit-width
space and map it to plain space character (found e.g. in text(9)).
