A bit of technical clarification:
Terminal emulators seem to default to lines ending in an explicit newline.
It's the implicit overflow (printing a letter that wraps to the next line)
which makes the previous line soft-wrapped, and a \e[K (clear to EOL) and
perhaps a few other similar sequences (e.g. character deletion) that makes
it hard-wrapped again.
Newlines are irrelevant, especially since it's often a CR LF so technically
the cursor is in the first column when it's moved to the next line.
I mistakenly omitted the fact that the "magic" also involves emitting that
\e[K before reprinting the last character of the command line, this is the
key to the expected behavior, as currently done with non-colored prompts
