[PATCH] pasting: when less than a line is pasted, allow automatic hard-wrapping

[Benno Schulenberg]

When --breaklonglines is in effect and ^U pasted just a short text
(anything that does not contain a newline), then act as if the short
text had been typed and hard-wrap the line when it became overlong.

This fulfills https://savannah.gnu.org/bugs/?61353.
