#1620 Possible WordStartPosition / WordEndPosition bug

[klo]

Consider this Lua function:

print(editor.CurrentPos..':'..editor:WordEndPosition(editor.CurrentPos))

If cursor is at the word end (current position is same as end position) then editor:WordEndPosition reports position larger by 1. If cursor is inside word, then reported word end position is correct.

The same faulty rule can be observed for editor:WordStartPosition, too.

It looks like something is forbidding editor.CurrentPos to be same with either or reported positioning functions.

This function looks at the character after the position, then searches forward for the next change in character class. They never look at the previous character. Its exposing the code Scintilla uses for the Ctrl+Right key.

Can not see the logic...

For example, I have document with content:

Hello World

If I place the cursor inside each word I get 0:5 and 6:11 respectively for WordStartPosition and WordEndPosition.
If I place the cursor after letter "o" in Hello, it's CurrentPos is 5 as expected, while WordEndPosition is reported 6 which is WordStartPosition of the next word.

Also if place the cursor after letter "d" in World, and if there is no space after it, I get 6:11, but if I add single space I get 6:12.

If this is how it is supposed to work then Ok.
Maybe just it does not make sense to my expectations.

That is how it is supposed to work, just like the Ctrl+Right key.
