This patch fixes a problem, which is that the caret was not placed where the source location information for the node is, but instead in a random position based on the indentation level.

The problem that the caret is not placed under the `=` sign, but instead at the front of the expression, feels like a different bug related to how source location information is computed throughout cpython for infix operators. I don't think it should be fixed in this bug, but rather in a follow-up.

Specifically, this fix (to make the printing actually respect the source location information) will also be required in order to fix the placement of the caret to under the = sign.
