ltmain.in. (ECHO): Audit for (and correct!) uses of $ECHO with more than one argument, which breaks when ECHO='printf %sn', and with possible `-' as first character of the argument, which breaks `print -r' and some implementations of `echo'. * config/ltmain.in, tests/defs.in, libtoolize.in (ECHO): Ditto.
