Pasting text ==> Error: Illegal argument: character must be non-negative

[rioj7]

After pasting some multi-line text block I got the following error (Developer Console)

Error: Illegal argument: character must be non-negative

It tries to create a vscode.Range with a negative character value on a line.

Looking at the code in toRangeDelta the variable charsDelta can become negative if the new range is shorter at the last line.
