in the bash 3.1 release, new options were added: -i -q -x
however, the doc/bashref.texi and doc/bash.1 files were not updated
to document these fun features
i've attached an updated patch based upon the ulimit.patch from Fedora
which documents these three options and adds two new ones ...
any reason to not include the -e (scheduling priority) and -r (rt
priority) options that Fedora has been using ?
-mike
Ripped from Fedora
Add support for RLIMIT_NICE/RLIMIT_RTPRIO and add missing documentation
for many other options
