  tests: quote 'like this', not `like this', as per GCS recommendation
  
  This patch converts the automake testsuite and related files, to
  the use of new quoting format 'like this' or "like this" rather
  than `like this'.
  
  This is done for consistency with the new recommendations in the GNU
  Coding Standards, and, well, because I've come to actually prefer
  the '...' and "..." quoting formats over the `...' one.
  
  * tests/README: Update quoting format throughout.  Remove some
  "excessive" use of quoting, and throw in minor rewording where
  appropriate.
  * tests/Makefile.am: Likewise, for comments.
  * tests/CheckListOfTests.am: Likewise.
  * tests/defs-static.in: Likewise.
  * tests/defs: Likewise.
  * tests/trivial-test-driver: Likewise.
  * Many tests/*.tap, tests/*.test and tests/*.sh files: Likewise,
  and for the diagnostic and informational messages as well.
  * tests/gen-testsuite-part: Likewise, and for the generated tests
  as well.
