Bug-Reference-ID:	<39c9472ddcf23881693380c4b895dd3799b45cec.camel@setenforce.one>
Bug-Reference-URL:	https://lists.gnu.org/archive/html/bug-bash/2026-05/msg00065.html

Bug-Description:

If readline handles a SIGWINCH and resizes its idea of the screen
dimensions, it needs to recompute the columns where the prompt wraps
lines every time, not just when the screen width decreases.

Patch (apply with `patch -p0'):
