gbranden pushed a commit to branch master
in repository groff.
commit 9f3ba1859ef8e737cc6bc40d46f288ad092d4b7d
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sat Aug 22 15:01:10 2020 +1000
Add regression test for Savannah #58992.
This test fails in the current state of tree (failure means honoring an
.ll request to set the line length prior to processing a man page).
groff was already ignoring an .ll request in the special case that it
was '65n' or a unit equivalent.
The next commit will make it pass.

+# Regression-test Savannah #58992.
+#
+# Our man macros should no longer attempt to read the .l register on
+# nroff devices to set the line length. That register may or may not
+# have been set by a user .ll request; we can't tell whether a value of
+# 65n came from nroff or the user.
+#
+# Instead, the LL register must be used to set the line length.
+#
+# In this test we _expect_ the .ll request to be ignored and overridden.
+# We choose a value that is not nroff's default nor man's default.
