Add 'r' flag (raw) for unquoted output

Browse Source 
By default, placeholder expressions are automatically quoted to ensure
they are safely passed as arguments to external programs.

The r flag ({r}, {r1}, etc.) disables this behavior, outputting the
evaluated value without quotes.

For example,

  echo 'foo   bar' | fzf --preview 'echo {} {r}'

The preview command becomes:

  echo 'foo   bar' foo   bar

Since `{r}` expands to unquoted "foo   bar", 'foo' and 'bar' are passed
as separate arguments.

**Use with caution** Unquoted output can lead to broken commands.

  echo "let's go" | fzf --preview 'echo {r}'
