Alas, this does not really work for me. When I get a fresh checkout and retry
the steps from the issue, I see

...removing jamgram.c

and everything is messed up. Looking at source, I see:

/* If the command was interrupted or failed and the target */
/* is not "precious", remove the targets */

if( status != EXEC_CMD_OK && !( cmd->rule->actions->flags & RULE_TOGETHER ) )

and that really makes no sense to me. What's relation between RULE_TOGETHER
and "precious"? Maybe, we should just introduce "PRECIOUS" buildin, which
will prevent deletion of target if action fails?
