I'd like one which looked up XXX_MAX somewhere (probably in the macro
file) and expanded to XXX_MAX, its implementation defined value, and some
connecting text. Can mdoc handle this? If not, there could be more
specialised macros for at least PATH_MAX and NAME_MAX. In *.2, there
are 46 references to 1023 (PATH_MAX or MAXPATHLEN - 1), 6 references to
1024 (PATH_MAX) and 49 references to 255 (NAME_MAX). NAME_MAX shouldn't
actually be defined, since it is fs-dependent. OTOH, POSIX.1 uses
{NAME_MAX} as an abreviation for "NAME_MAX if that is defined, else the
fs-dependent value given by pathconf(path, _PC_NAME_MAX) or fpathconf()
where `path' is ...". The macro should handle some of this.
