change-preview-window to take multiple option sets separated by '|'

Browse Source 
So you can "rotate" through the different options with a single binding.

  fzf --preview 'cat {}' \
      --bind 'ctrl-/:change-preview-window(70%|down,40%,border-horizontal|hidden|)'

.SS CHANGE PREVIEW WINDOW ATTRIBUTES
\fBchange-preview-window\fR action can be used to change the properties of the
preview window. Unlike the \fB--preview-window\fR option, you can specify
multiple sets of options separated by '|' characters.
e.g.
# Rotate through the options using CTRL-/
fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(right,70%|down,40%,border-horizontal|hidden|right)'
# The default properties given by `--preview-window` are inherited, so an empty string in the list is interpreted as the default
fzf --preview 'cat {}' --preview-window 'right,40%,border-left' --bind 'ctrl-/:change-preview-window(70%|down,border-top|hidden|)'
# This is equivalent to toggle-preview action
fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(hidden|)'
