Looks good.
I've found that doesn't work when there's also a [build-menu] section in a user filetype file.
Yes, the docs do actually say `[build_menu]` overrides on the line after one you changed (original line 4304) :grin:.
A single file is not really supposed to have both `[build_menu]` (the "new" settings) and `[build_settings]` (the "old" settings), they don't have exactly the same semantics so their overlap is possibly confused.
