I noticed incorrect formatting of the URL examples in OpenBSD autoinstall(8) man page when rendered with GNU man / nroff
(version 1.22.4, Archlinux package).[1]

I was able to cut it down to the following minimal reproducer:

.Dd bug
.Dt TEST 7
.Os
.Sh NAME
.Nm test
.Nd illustration of mdoc .Bd macro
.Sm off
.Bd -unfilled
.No line1
line2
line3
.Ed

line1 and line2 are run together in output of GNU "nroff -mdoc".

Removing either the .Sm or the .No macro makes GNU troff produce the (in my understanding, and matching OpenBSD mandoc) correct rendering with all three lines on separate lines.
