[Bug translator/11274] New: stap-client doesn't understand "--"

["jistone at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

Using getopt, "--" is a special argument that stops further processing. 
However, stap-client appears not to handle this, so it can be tricked into doing
things that it shouldn't.


$ stap-client -l syscall.open* -- -p5
syscall.open
syscall.openat
ERROR: Unable to canonicalize path "stap_8052.ko": No such file or directory
Retrying, after attempted removal of module stap_8052 (rc -1)
ERROR: Unable to canonicalize path "stap_8052.ko": No such file or directory

(staprun can't load a module we didn't actually build)


$ stap-client -l syscall.open* -- -rfoo
/usr/local/bin/stap-client: ERROR: Unable to connect to a server

(no server on my network claims to build for kernel foo)


AFAICT the server side correctly ignores these, so this is only an issue of what
is attempted locally.
