I like the changes. Just a few more comments for clarification.
File Documentation/notation/input.itely (right):
Documentation/notation/input.itely:2847: Note: @code{set-global-fonts}
can change not only the notation fonts
Maybe change the wording slightly:

"Note: Each call to @code{set-global-fonts} completely resets both the
main notation and text fonts. If any category is left unspecified, then
the default font will be used for that category.

Each call to @code{set-global-fonts} changes the fonts for each
@code{\book} that follows it, whether created explicitly or implicitly.
This means that each @code{\book} can have its own set of main fonts by
calling @code{set-global-fonts} before it."
Documentation/notation/input.itely:2881: Note: The only allowed font
names must have the
I would reword this to be a bit more specific so there's no confusion
about what is/isn't expected:

"Note: At the moment, LilyPond expects the font file names to have the
following suffixes, all of which must be present in the above
installation folder(s) to work properly:"

The only caveat is that the user doesn't technically need to have BOTH
the music font set (with the -11, -13, -14, -16, -18, -20, -23, and -26
suffixes) AND a brace font (with the -brace suffix) for one or the other
to work, but the music font set must have a file for ALL of those
suffixes and the brace font must have its suffix.

The reason for this is that the internal functions are hard-wired to
require this, but can be modified quite easily to allow for more
flexibility in the number of music font files. They could also be
changed so the brace font no longer needs its -brace suffix, but maybe
it should be kept that way since there's only one brace font file. I
have configured the functions to allow this on my machine and haven't
seen any issues in functionality.
Documentation/notation/input.itely:2884: That is,
@address@hidden, @address@hidden,
I think it makes sense to be specific here, with something like "For
example, @file{emmentaler-11.otf}" instead of "That is,
File Documentation/notation/text.itely (right):
Documentation/notation/text.itely:1618: as the above
@code{make-pango-font-tree} example.
Since users are now using other music fonts, I think we better add a
note to make-pango-font-tree that says this resets the music font to
Emmentaler so that no one is surprised when this happens. Should
make-pango-font-tree be deprecated in favor of set-global-fonts?
Documentation/notation/text.itely:1644: #:brace "emmentaler"
; default
It is important to note that the user does NOT specify the suffix of the
font (e.g, "emmentaler-18" and "emmentaler-brace"), only the root font
_file name_ "emmentaler" and NOT the internal font name "Emmentaler".
The suffixes are added internally when the font tree is being created
and looking up the font files. A simple note to say the suffixes are not
needed (indeed, will cause an error if given) would suffice, IMO. This
only applies to the #:music and #:brace strings. The text fonts expect
the internal font names.
Documentation/notation/text.itely:1654: Each call of
@code{set-global-fonts} affects only the following book(s).
Maybe reword this paragraph a little:

"Each call of @code{set-global-fonts} affects each @code{\book} blocks
that follow it.

If there are multiple @code{\book} blocks and you want to use different
fonts for each, simply call @code{set-global-fonts} again, like this:"
