-
-      <p>This was a regression introduced in ncurses 6.2 (<a href=
-      "https://lists.gnu.org/archive/html/bug-ncurses/2020-03/msg00000.html">reported</a>

+      <p>Text files contain no embedded nulls. Also, they end with
+      a newline. Feeding <strong>tic</strong> non-text files
+      exposed a few cases where the program did not check for those

+      <p>Fixing the limit-checks (first) found a problem with

+      terminal description. In merging two terminal descriptions
+      (i.e., the &ldquo;use=&rdquo; feature), <strong>tic</strong>

+      <p>The checks for non-text files are improved (i.e., embedded
