+The status of any error in a pipeline or a backquote expansion that is
+propagated as a result `status', unless `tcsh_posix_status'
+variable is set, and only the last command status is taken in account
+(the latter is default behaviour in POSIX-like shells). If it terminated
abnormally, then 0200 is added to the status. Builtin commands
which fail return exit status `1', all other builtin commands
return status `0'.
