fix: account for caret notation width in text wrapping

Browse Source

Control characters displayed in caret notation (e.g. ^@ for NUL)
occupy 2 terminal columns, but the width calculation treated them
as 0-width. Add a char_width() helper that returns 2 for control
characters, fixing incorrect line wrapping with --binary=as-text.

Fixes #3631
