## Description
`vim.split` would split `""` into `{ "" }`, causing `table.concat` to
output `",eol: "`.
Resolved by using `vim.tbl_filter` to filter out empty strings before
applying `table.concat`.
## Description
This is an initial commit for trying to add horizontal scrolling for the
picker preview window.
Known issue: when scrolling horizontally with scope indent, the indent
chars persist in the preview window and don't disappear as they
should...
Edit:
I just realized this happens only when we are previewing a buffer that
is already open. Only in that case the indents are being rendered... if
we are previewing a file that is not currently open the indents don't
get rendered and therefore there is no issue. Maybe this is a bug?
Should we prevent rendering of the indent guides in the preview window?

## Description
More info coming tomorrow.
In short:
- very fast. pretty much realtime filtering/sorting in huge repos (like
1.7 million files)
- extensible
- easy to customize the layout (and lots of presets) with
`snacks.layout`
- simple to create custom pickers
- `vim.ui.select`
- lots of builtin pickers
- uses treesitter highlighting wherever it makes sense
- fast lua fuzzy matcher which supports the [fzf
syntax](https://junegunn.github.io/fzf/search-syntax/) and additionally
supports field filters, like `file:lua$ 'function`
There's no snacks picker command, just use lua.
```lua
-- all pickers
Snacks.picker()
-- run files picker
Snacks.picker.files(opts)
Snacks.picker.pick("files", opts)
Snacks.picker.pick({source = "files", ...})
```

## Todo
- [x] issue with preview loc not always correct when scrolling fast in
list (probably due to `snacks.scroll`)
- [x] `grep` (`live_grep`) is sometimes too fast in large repos and can
impact ui rendering. Not very noticeable, but something I want to look
at.
- [x] docs
- [x] treesitter highlights are broken. Messed something up somewhere
