sh: Allow EV_EXIT through function calls, make {...} <redir more consistent. If EV_EXIT causes an exit, use the exception mechanism to unwind redirections and local variables. This way, if the final command is a redirected command, an EXIT trap now executes without the redirections. Because of these changes, EV_EXIT can now be inherited by the body of a function, so do so. This means that a function no longer prevents a fork before an exec being skipped, such as in f() { head -1 /etc/passwd; }; echo $(f) Wrapping a single builtin in a function may still cause an otherwise unnecessary fork with command substitution, however. An exit command or -e failure still invokes the EXIT trap with the original redirections and local variables in place. Note: this depends on SHELLPROC being gone. A SHELLPROC depended on keeping the redirections and local variables and only cleaning up the state to restore them. 2011-04-23 22:28:56 +00:00			`# $FreeBSD$`
