Problem: If spellfile is missing, then "set spell" in modeline/sandbox
fails with a non-obvious error.
Solution: Check for sandbox early and give a meaningful error.
Fixes#11359
Test case:
# test.latex has `% vim: set spelllang=hu:`
# no spell file for `hu` yet!
nvim -u NORC --cmd 'autocmd FileType tex setlocal spell' --cmd 'set modeline' test.latex
Before:
No spell file for "hu" in utf-8
Download it?

- Always auto-create spell/ directory, don't ask.
- Don't ask where to put .spl file if only 1 choice exists.
- Always download .sug file, don't ask.
- Use blackhole register for :delete and :g//d.
- Formatting: expand tabs.
Add missing parentheses and whatnot, move dangling comment, etc. Some
specific items worth mentioning:
Fixed some references to non-existent tags, found via `make html`
msgpack_rpc/channel.c:
ELOG already prefixes each line with "error @ ..."
