When I perform the same action in Vim, I get a different result. Is this intentional?
- Enter
aaa bbc - Place the cursor on
c - Enter
2d3h - Only

Nice catch, looks like I misunderstood the correct behavior.
Updated the test to match with readline, fix implementation to use 2*3 = 6 as vi_arg in that case
vi_arg and vi_waiting_operator_arg should be multiplied

Can you split the input? This input is a bit complex. 😵💫

For my learning: Why pass byte_pointer_diff? Are multi-byte characters allowed?

Yes. multi-byte characters are allowed.
vi_waiting_operator will do
- save cursor position (represented by
@byte_pointer) - accept VI_MOTIONS. cursor position moves. (
@line_indexdoes not change) - Run an action(==
@vi_waiting_operator) to a text between old cursor position and new cursor position
Current cursor position can be retrieved from @byte_pointer, so we need to pass old cursor_position or difference between old and new curspor_position
The original implementation selected diff, and this pull request follows it.
And we can choose how to represent cursor position: byte_pointer, string size, grapheme_cluster size width in column when rendered to terminal. Using byte_position is easiest because we don't need to translate @byte_pointer to another representation form.

I understood. Thanks for explaining!

For my learning: So all we need to do here is initialize vi_arg, why don't we call cleanup_waiting?

cleanup_waiting is to clear @waiting_proc relevant things. @waiting_proc is a mechanism to override input_key.
For example, C-h is normally handled by em_delete_prev_char, but in incremental search mode, it is handled by waiting_proc.
On the other hand, @vi_arg is not related to waiting_proc mechanism. It is passed to other normal ed_xxx vi_xxx em_xxx methods as a keyword parameter.

Example: 2d3fo will do dfo (delete to next char o) 6 times,
2: ed_argument_digit sets @vi_arg = 2
d: vi_delete_meta sets @vi_waiting_operator, @vi_waiting_operator_arg = :vi_delete_meta_confirm, 2
3: ed_argument_digit sets @vi_arg = 3
f: vi_next_char sets @waiting_proc. run_for_operators should skips calling cleanup_waiting when @waiting_proc is set.
o: @vi_arg is set to 6, @waiting_proc is called (cursor moves), @vi_waiting_operator deletes text between cursor movement.
(I added this to test case)

I misunderstood the relationship between @waiting_operator and @vi_waiting_operator. Thanks!

Test will conflict with #645
Fixes #605
waiting_proc
Most waiting_proc will be cancelled when ARROW keys (and other symbol key) is pressed, but Reline did not implement cancel
Fixes except ed_quoted_insert.
waiting_operator_proc
Vi mode's waiting_operator_proc was complex.
Reline's problem with waiting_operator
df_does not terminate delete_metaddshould clear lineccshould clear linedcdycdcyydycyyshould cancel waiting_operator3d5h, 5 should be used as@vi_argbut Reline does notFixes all of them.
