In the list of macros in groff_mm(7) the macro names in the headings of paragraphs in the "Macros" section are never specified with a leading period. In similar cases in groff_ms(7) and groff_man(7) the periods are always used. Also, in the text of paragraphs groff_mm(7)'s use of periods before macro names is inconsistent: sometimes it uses them, and sometimes it does not. You can see this in the paragraph for GETST, where in the body refers to ".SETR" with the period, and to "GETST" and "INITR" without the period.
This has a practical consequence: it is much harder to find all mentions of a macro name when the leading period is omitted. For instance, you can easily find the one occurrence of the "P" macro in groff_mm(7) where it is specified with a leading period, but finding all the other occurrences of the "P" macro are hard, because searching finds the "P"s in the middle of other macro names and in the body text. So, does anybody think this warrants changing the man page to match the other macro package man pages? If no-one else has plans for changing the mm man page I could produce a diff... -- T.
