+       Make strip.sed operate only if given permission.
+
+       * tmac/strip.sed: Do nothing whatsoever to any input file that
+       lacks a line matching "%beginstrip%".  This implements a
+       contract between the macro file writer and the stripper script
+       {roff input is not parseable with crude weaponry like regular
+       expressions}.  In practice, most of the changes performed by the
+       script were already in a block enforcing this.  My changes:
+       - Stop unconditionally inserting a roff comment noting the
+         reader of stripping at line 2.  Instead, replace the line
+         matching "%beginstrip%" with this comment if and only if it
+         is present.
+       - Stop deleting lines containing only the empty request if
+         they occur before "%beginstrip%".
+       - Tweak the wording of the roff comment.
+       - Remove comment within the sed script; see
+         https://lists.gnu.org/archive/html/groff/2017-11/msg00057.html
+         and the sed section of "Limitations of Usual Tools" in the
+         GNU Autoconf Manual.
