BrowseUI / CAutoComplete: double click on a word selects leading blank and stops too early

reactos-bootcd-0.4.15-dev-7434-g8b5c5fb-x86-gcc-lin-dbg

While investigating on CORE-19423

• Type "d dd" in Start > Run
• Double click on the "dd" part with mouse cursor on the right of the text not to fall into CORE-19423
• " dd" gets selected (<BLANK>dd)
• Expected result "dd" to get selected (no "<BLANK>")
• notepad is not affected

Problem comes from EDIT_CallWordBreakProc : 

• with EDIT_WordBreakProc (notepad). Good code in EDIT_WordBreakProc, as it returns "2" for "d dd" in https://git.reactos.org/?p=reactos.git;a=blob;f=dll/win32/comctl32/edit.c;hb=cbc3ee2287c1972ac8257da60388a5de9ea6c0e5#l238
• with es->word_break_proc (Start > run). Guilty is then EditWordBreakProcW, as it returns "1" for "d dd" in dll/win32/browseui/CAutoComplete.cpp

Similarly testing with 

<BLANK>TEST<BLANK><BLANK><BLANK>REACTOS

should select "TEST<BLANK><BLANK><BLANK>"

See : ROS-screen0.webm

Guilty code is https://github.com/reactos/reactos/commit/c19d9df2593d6376f783dae78ba67fe53280fa4a from katayama_hirofumi_mz
