I don't know > those technical terms. \f introduces a font escape sequence, which changes the font being used to set the text. They go way back to 1970s AT&T troff. Italic correction escapes are a groff innovation for a typographical concept of ancient vintage. They are spelled "\," and "\/" (these are the sorts of names you come up with when you run out of room in a one-character name space that has to be input from an ASCII keyboard). All are documented in groff(7)[1]. The italic correction escapes are discussed at greater length in groff_diff(7)[2] since they would be new to AT&T troff veterans. > Ahh, I used mgroff(1) (mental groff).

Well...it's not _ignored_, it's a macro--it gets interpolated and interpreted. It just, in this case, doesn't do much if anything that isn't redundant. > Since almost when I started here, I'm trying to have the man-pages be > consistent across all of the pages, both in terms of source code and > rendered output.
