- `:write ++p foo/bar/baz.txt` should create parent directories `foo/bar/` if
they do not exist
- Note: `:foo ++…` is usually for options. No existing options have
a single-char abbreviation (presumably by design), so it's safe to
special-case `++p` here.
- Same for `writefile(…, 'foo/bar/baz.txt', 'p')`
- `BufWriteCmd` can see the ++p flag via `v:cmdarg`.
