multiple bind --expect broken in recent releases (up to 0.13)

[ibhagwan]

The below works with v10.0.4 but doesn't work with v0.12/v0.13:

sk --expect="ctrl-y,ctrl-g"

Recent releases only work with one key in --expect, both below work:

sk --expect="ctrl-y"                    # Works with only one key
sk --expect="ctrl-y" --expect="ctrl-g"  # Works if split into multiple flags

It might also be worth noting that fzf recently moved away from the --expect approach (had issues combining actions with expect, see junegunn/fzf#3810) and instead added the more versatile print(...) action so it's now possible to emulate (and expand) on --expect with:

For example, using ctrl-q to select-all+accept without losing the bind context in the final results

fzf --bind ctrl-q:select-all+print(ctrl-q)+accept

Same issue with --nth and similar arguments
