src/cmd/ksh93/bltins/print.c: - Rename the unlisted and misleadingly named SHOPT_ECHOE option (which disables, not enables, 'echo -e') to SHOPT_NOECHOE. src/cmd/ksh93/SHOPT.sh: - Add the SHOPT_NOECHOE and SHOPT_TEST_L compile time options to the list of SHOPT options. Since there is a probe for TEST_L, set it to probe (empty) by default. NOECHE is off by default. src/cmd/ksh93/features/options: - Small bugfix: Allow SHOPT_TEST_L to be manually enabled on systems that don't support '$(whence -p test) -l /foo'. - Add a comment describing the SHOPT_MULTIBYTE feature test and separate it from the SHOPT_DEVFD test.
