Description of problem:

Using command line option "-c" to specify a command to run during the stap session has the undocumented side-effect of setting target() to the pid of the command ran. This is actually a good thing and should be documented. :)

Version-Release number of selected component (if applicable):

systemtap-1.4-2.fc14.x86_64, very likely F15 and rawhide as well.

How reproducible:

Always.

Steps to Reproduce:

$ sudo stap -e 'probe begin { printf("%d\n", target()); }
probe kernel.function("do_exit") {
  printf("%s(%d) called do_exit\n", execname(), pid());
}' -c /bin/true 

31688
true(31688) called do_exit

$ man stap
[find no mention of target() on "-c" section]

Actual results:

It is not documented on manpage and other documentation.

Expected results:

It should be documented on manpage and other documentation.

Additional info:

Maybe a bugzilla was not the best way to pursue this?
