jilles 2011-06-12 23:06:04 UTC FreeBSD src repository Modified files: bin/sh eval.c expand.c expand.h jobs.c sh.1 var.c var.h Log: SVN rev 223024 on 2011-06-12 23:06:04Z by jilles sh: Save/restore changed variables in optimized command substitution. In optimized command substitution, save and restore any variables changed by expansions (${var=value} and $((var=assigned))), instead of trying to determine if an expansion may cause such changes. If $! is referenced in optimized command substitution, do not cause jobs to be remembered longer. This fixes $(jobs $!) again, simplifies the man page and shortens the code.
