Merge branch 'vr/use-our-perl-in-tests' into maint

Some implementations of Perl terminates "lines" with CRLF even when
the script is operating on just a sequence of bytes.  Make sure to
use "$PERL_PATH", the version of Perl the user told Git to use, in
our tests to avoid unnecessary breakages in tests.

* vr/use-our-perl-in-tests:
  t/README: add a bit more Don'ts
  tests: enclose $PERL_PATH in double quotes
  t/test-lib.sh: export PERL_PATH for use in scripts
  t: Replace 'perl' by $PERL_PATH

+
+ - chdir around in tests.  It is not sufficient to chdir to

+   the test, as any intermediate step can fail and abort the test,

 of the test_* functions (see the "Test harness library" section
