* libltdl/config/general.m4sh: Replace all uses of `$ECHO "X..." | $Xsed' with `$ECHO "..." | $SED', and employ further trivial simplifications. Replace $ECHO with echo where appropriate. (func_echo_all): New function. * libltdl/config/getopt.m4sh: Likewise simplifications. * libltdl/config/ltmain.m4sh: Likewise. * libltdl/m4/libtool.m4: Likewise. (LT_CMD_MAX_LEN): Use func_fallback_echo, to ensure that the command line is passed through an exec* function. * libtoolize.m4sh: Likewise simplifications. Use func_echo_all to implement --dry-run. * tests/defs.m4sh: Likewise simplifications. * tests/quote.test: Likewise simplifications. Signed-off-by: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
