+ 
+       Modernize, improve and extend tests `suffix*.test'.
+       * tests/suffix3.test: Enable `errexit' shell flag, and related
+       changes.
+       * tests/suffix4.test: Likewise.
+       * tests/suffix6.test: Likewise, and do not create a useless dummy
+       source file.
+       * tests/suffix7.test: Likewise.
+       * tests/suffix5.test: Enable `errexit' shell flag, and related
+       changes.  Make grepping of Makefile.in slighty stricter.
+       * tests/suffix.test: Enable `errexit' shell flag, and related
+       changes.  Also, do not redirect grep output to /dev/null, as this
+       might unmotivatedly hide useful information.
+       * tests/suffix2.test: Move setting of `errexit' shell flag earlier
+       in the script (just after inclusion of ./defs).  Use a more
+       idiomatic way to count text occurrences in Makefile.in with
+       grep.  Do not create useless dummy source files.
+       * tests/suffix10.test: Ensure verbose printing of captured make
+       stdout.  Minor cosmetic changes.
+       * tests/suffix8.test: Likewise.  Also, drop useless call to the
+       env(1) utility, and make grepping of make output stricter by using
+       $FGREP rather than plain grep.
+       * tests/suffix11.test: Likewise.
+       * tests/suffix12.test: Likewise.
+       * tests/suffix9.test: Prefet cat + here-doc over echo to append to
+       the `configure.in' stub.  Cosmetic changes.
+       * tests/suffix13.test: Cosmetic spacing change.
+

+ 
+       Add useful comment in test script ext.test.
+       * tests/ext.test: Add a comment explaining why an apparently
+       useless `if' statement is indeed required.

        Add useful comment in test script obsolete.test.
        * tests/obsolte.test: Add a comment explaining why we need
        an indirection in adding $AUTOUPDATE to $required.
