This documents how to go about adding a macro to mdoc.3.

(1) Add the macro to the #define list in mdoc.h.
(2) Add the macro to __mdoc_macronames in mdoc.c.
(3) Add the macro to __mdoc_macros in mdoc.c.
(4) Add the macro to mdoc_valids in validate.c.
(5) Add the macro to mdoc_actions in action.c.
(6) Add the macro to mdoc_argflags in argv.c.
(7) Modify the hash routine in hash.c (may not be required).

If the macro has arguments:

(1) Add arguments to the #define list in mdoc.h.
(2) Add the arguments to __mdoc_argnames in mdoc.c.
(3) Modify parts of argv.c (lookup() and mdoc_args()).

You'll certainly want to change the front-ends:

(1) Add the macro to __termacts in term.c.
