the worrysome part is what happens with make: andres@pote:~ $ echo '/nonexsistent:;@echo -e hello' | make -f- | vis -e hello\$ andres@pote:~ $ echo '/nonexsistent:;@echo -e hello;' | make -f- | vis hello\$ this is due to the optimization to fork+exec instead of shell when there are no meta characters. the second makefile has `;', so the optimization doesn't get triggered what is the problem? 2 echos that disagree or the optimization itself? are the calls coming from *INSIDE* the house?
