This fork is meant to provide a patched AutoCompletion.cpp file. All other files are highly outdated.
It fixes this bug: notepad-plus-plus#1038
Example bugged official version with bracket autocompletion:
Writing (a( results in (a() - the second bracket is not closed. This patched version fixes this.
See issue linked above. Replace the .cpp file, and make a unicode debug build. A unicode release build will crash, because it lacks a signature.
