Re: [PATCH v5 0/10] MR2637: winex11: Use messages instead of user callbacks and handle them in the default IME UI window procedure.

[Byeongsik Jeon (＠bsjeon)]

There is a issue when calculating flags in input_context_set_comp_str().

With purely this MR applied, I type 'nihongo\<SPACE\>n' with ibus-anthy or ibus-mozc.

Below is the trace output. Note the lparam values.
The analysis took a long time because I thought something else was causing it.

```
00d0:trace:imm:input_context_set_comp_str ctx 00EF0690, result 1, str L"\65e5\672c\8a9e"
00d0:trace:imm:ime_send_message himc 00010064, msg 0x10f, wparam 0x65e5, lparam 0x18b8

00d0:trace:imm:input_context_set_comp_str ctx 00EF0690, result 0, str L"n"
00d0:trace:imm:ime_send_message himc 00010064, msg 0x10f, wparam 0x6e, lparam 0x1838
```
