  if (for some weird reason) i wanted to define a multi-level
subsection, is there any benefit to using periods as i did above, as
opposed to any other delimiting character? apparently, running this:

  $ git config --global a.b_c_d.e rday

dumps this into my ~/.gitconfig:

  [a "b_c_d"]
	e = rday

if i wanted to do something this admittedly awkward, would using
periods give me some benefit related to, i don't know, regex matching,
as compared to using a different character? or am i just way
overthinking this? is anyone out there actually taking advantage of
multi-level subsections?
