Apologies on behalf of my inferior cognitive faculty, but I do not see a
solution to my problem in those options (perhaps merely a means to it).
Between OVERVIEW, CONTENT, SHOWALL, SHOWEVERYTHING, which == "allow me to
save and reopen the buffer in its current configuration."
From what I can gather from limited reading comprehension, these are still
general settings, i.e., ALL headlines will be opened; ALL drawers will be
opened; ALL text will be exposed.
What I want is to just have those things exposed that I exposed in my
particular session.
