[Bug runtime/11325] New: Spaces and exclamation marks invalid as module arguments

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

Examples:

$ stap -p4 -m mod1 -e 'global var1="foo";  probe  begin{printf("%s\n", var1);
exit()}'

$ staprun mod1.ko var1="hello!"
bash: !": event not found

$ staprun mod1.ko var1="hello world"
Error inserting module '/notnfs/chwang/systemtap/mod1.ko': Unknown symbol in module
Retrying, after attempted removal of module mod1 (rc -1)
Error inserting module '/notnfs/chwang/systemtap/mod1.ko': Unknown symbol in module


Also, escaping the exclamation mark results in the escape character also being
printed:

$ staprun mod1.ko var1="hello\!"
hello\!
