limit columns to line_length

[mstuehn]

(neo)vim provides a mode "virtualedit=all" where the cursor can be placed behind the last character of the line. Limit the column to line_lenght prevents raising a ValueError

This is unfortunately not fixing the issue, it's simply circumventing it. If I were to merge this, things like not will complete to NotImplemented instead of having all global completions. Goto will also act weird and so on. This is unfortunately not that simple. As I said before, this is unfortunately not a simple change.

Plus, this also needs tests.

Ah, ok. The patch worked ok for me, but i have to admit, that i do not fully understand the implications.
Sorry for the noise; unfortunately i do not have the capabilities to provide a proper solution.
