Yes, this one.  I think.

I'm not clear about the difference between this and the next one.

In current GDP terminology, these are "Text scripts".

I'd like to say something like this... but I don't know if it's
true or not:
Fundamentally, all text is produced via \markup.  However, there
is a shortcut for defining simple pieces of text: you can write
"foo bar".  Internally, this expands to
\markup{ \line { foo bar }}.

That way, we don't need to re-explain about how to create text
every time we introduce text scripts, headers, instrument names,
metronome markings, etc.  We could just say "The title is markup
text" and people will know that they can use either title = "foo"
or title = \markup{ \fancy \formatting foo }.

*as far as I know*, anything in lilypond that accepts "blah blah"
also accepts \markup.

With the "atomic", I was trying to get to a general explanation
for things like this:
\markup {
  \center-align {
    "bar baz"
    "rtfm you idiot"

where each line in this example is an "atom", and is treated as
indivisible by center-align (no need to add \line{ ...} around
entries with spaces in them).

No; \version is a special case... let me rephase my earlier
statement: as far as I know, all lilypnod commands that accepts
*arbitrary* pieces of text inside "" also accept \markup.

It's hard to argue against this.
