That is because of the wrong exit code of loadenv. In do_loadenv we have
return envfs_load(filename, dirname);
which returns negative numbers as errors. The shell interpretes negative
numbers as return codes from commands as 'exit', so this should really be
return envfs_load(filename, dirname) ? 1 : 0;
Probably other commands have this bug aswell.
