No idea - I'm not an asciidoc whiz.  How would I tell (or can someone
else offer some advice)?

POSIX requires that "find . -name '*'" not use FNM_PERIOD, and I
actually like the consistency with find(1).  In other words, I would
complain (then go with group consensus, if my complaint is in the
minority) that it is a step backwards to tighten the match, where the short:

  dir/*

would have to become the much longer

  dir/*
  dir/.[!.]
  dir/.??*

to properly exclude all except '.' and '..', or

  dir/*
  dir/.*

if '.' and '..' are already special to the pattern matching.
