vim-patch:76db9e076318 (#21013)

Update runtime files

76db9e0763

- `col()`'s example was changed to use `:echowin` so that the message can be
  seen with `showmode`. Use "\n" to force a hit-enter instead as `:echowin`
  isn't ported.
- Replace interpolated string usage in syntax/modula3.vim (not ported).
- Add a space after the `wincmd =` examples in `*CTRL-W_=*` so that the inlined
  code is highlighted properly when followed by a full stop.
