f37c181b29 43008: Improve code to remove privileges. 
Remove warnings of unused values as we always check the finally

Put segid before setuid as the setgid could fail if UID
no longer privileged.

5f6a52c06c 42156: new CHECK_RUNNING_JOBS option demanded by bash groupies 
Also new job options.

Also suppress debug error if rows or columns are reported as zero as
this is normal without a physical terminal.

for no "+=" and no GLOB_ASSIGN.

Documented in typeset builtin doc and mentioned in release notes.

Enabled by default, can be turned off by "disable -r" with typeset
family of commands.
