Eventual bugs in plugins with Notepad++ v8.4.x

[donho]

I’ve got some complains for the issues of some plugins with Notepad++ v8.4.x - these plugins in question have no problem with Notepad++ v8.3.3, so users think it’s a Notepad++ regression.

It’s due to updating Scintilla (one of components used by Notepad++) since v8.4.
The bug doesn’t come from Notepad++ : Scintilla has had changed the behaviour of its API SCI_GETTEXT, SCI_GETSELTEXT, and SCI_GETCURLINE from version 4 to version 5, hence this problem:

For plugins which use SCI_GETTEXT, SCI_GETSELTEXT, and SCI_GETCURLINE, the fix of this problem is to add 1 (character) to the length result of these 3 API, to make the plugin rework correctly under Notepad++ v8.4 and later versions.
