Because Elixir source code can contain `|`, the removed substitution
sometimes broke `lsp_document_symbols()`.
Example:
```
E5108: Error executing lua ...packer/start/telescope.nvim/lua/telescope/make_entry.lua:392: attempt to concatenate local 'symbol_name' (a nil value)

Closes#874
* feat: extend functionality of `entry_display.create`
- now allows passing functions or fractional values to `width` option
* refactor: cache `width` instead of results window size
* feat: use new `width` functionality for more entry makers
* fix: action mt so we can again concat actions from two different tables
- without actually changing the public interface
- without having a local table that keeps track of all actions
* this should clear actions now
we never actually called this function which is kinda a problem because
we never cleaned up previous mapping stores.
We can also make a better mappings store which has access to the keys
sequences which would help the showing actions part
* bugfix
* that should now clear everything
only tests left i think
* more tests
* cleanup
* hack: make sure all actions get cleared
* fix: finish docs and remove mistakes from merge
* fix: change order of `popup` changes based on type of change
- removes "flash" issue where popups don't update in sync
* feat: add hide / unhide preview or results and prompt
* fix edit actions while only preview window is active
* add option to start telescope without previewer -> "disable_previewer_at_startup"
* remove hide / unhide prompt and resutls, improve hide / unhide preview
* fix tests - check if popup window should be created with borders - popup.create does not support setting borderhighlight and border=false
* allow toggle preview even if preview is set to false
* reuse recalculate_layout in hide / unhide preview
* add docs to toggle preview
* check if preview window is valid window
* remove unnecessary changes
* cleanup, remove unnecessary changes
* close all previewers, refactor toggle preview code
[docgen] Update doc/telescope.txt
skip-checks: true
Files opened by LSPs are listed with a trailing `line 0` instead of a date like files opened by the user.
Use this behavior to filter out buffers that should not be displayed in oldfiles.
* WIP: recalculate picker layout on `VimResized`
* refactor: `popup.resize` -> `popup.move`
* fix: scroll to the correct place after resize
* fix: update positioning in results buffer
* fix: completely redraw results buffer on resize
* fix: handle preview enable/disable
* fix: work with scrolling
* docs: add plan for `toggle_padding`
* refactor: factor out creation of picker windows
* refactor: pass highlights directly to popup_create
* refactor: remove lines update and factor out scroll repositioning
