Up to you. Lots of things should be changed to say something like
{PATH_MAX} (not PATH_MAX) eventually. {PATH_MAX} is POSIX's markup
for the the value that is PATH_MAX if PATH_MAX is defined and
pathconf(mumble) in general. Most man pages don't even use MAXPATHLEN
yet. They hard-code MAXPATHLEN - 1 as 1023.
