Our error marking code: ``` function foobar ^~~~~~~^ ``` runs fish_wcswidth to figure out how wide the squiggly line should be. That function returns -1 when it runs into a codepoint that wcwidth returns -1 for, so the marking would stop at a single `^`. In some cases, this happens because the error range includes a newline. Since we already find the end of the line, and can only mark one line, we clamp the squiggles at the end of that line. This improves some markings. See discussion in #12171
