Dear Maintainer,

As per SUS Utility syntax guideline 5[0], command-line utility should allow
multiple arguments to be grouped behind single `-` delimiter.

I have yet to come across the *nix utility which doesn't follow this
convention. Can we please honor the Single Unix Specification?

$ chkrootkit -qn
Usage: ./chkrootkit [options] [test ...]
Options:
        -h                show this help and exit
        -V                show version information and exit
        -l                show available tests and exit
        -d                debug
        -q                quiet mode
        -x                expert mode
        -r dir            use dir as the root directory
        -p dir1:dir2:dirN path for the external commands used by chkrootkit
        -n                skip NFS mounted dirs
$ chkrootkit -q -n
<False positives>
$

allow

This is a valid request and would be reasonably straightforward for someone
to implement. The only complication is that Debian has added at least one
option over the years ( -s) so implementing this will require changes to
several other patches: it cant just be a simple patch to chkrootkit but
needs to update any existing patch that touches options.

So im not personally going to work on this any time soon. But patches are
welcome.
