Issues about Auto Completion Ignore Case

[lifenjoiner]

There should be 2:

1. Uppercase and lowercase are equal, while dictionary generating. Only the 1st word among different forms is adopted. In practice, ALL should be adopted, but sorted and matched ignoring case while typing.
2. The 2nd item of the matching results is focused by default, rather than the 1st one. Only ESC is the way to input exactly what is typed.

1. can be solved by using custom string comparison function (e.g. do case insensitive comparison first, then case sensitive comparison), CompareNCaseInsensitive() used in scintilla\src\AutoComplete.cxx also needs updating.
2. related to https://github.com/zufuliu/notepad2/blob/5258246f7685b32004d41c0d6d0a99613ccff6fe/src/EditAutoC.c#L1659-L1663
   change the if to SciCall_AutoCSetCaseInsensitiveBehaviour(bIgnoreCase) make it works.

Implemented by f66089f (except word list is sorted case sensitively).

[zufuliu]

Word list is actually sorted "randomly": first four letters sorted case insensitively (by WL_OrderFunc), then case sensitively (by WL_strcmp):

[zufuliu]

Removed from v4.23.06 milestone as first issue is not fixed: use of WL_OrderFunc to comparison still cause word less than five letters to lose.

👍 Didn't notice that.

It would be convenient if the words order is grouped case sensitive for "Ignore Case", considering the matching rate.
I guess you see what I mean. Case insensitive for different words, and then case sensitive for different cases of the "same" words. Seems not easy to do.

And still case sensitive for case sensitive.

Is this expected? I don't know.

It's result from following code:
