admit1: shebang scripts get a different proc title

When we run a shebang'd script directly, its process title expands out
to the path of the script interpreter (pulled from the shebang line)
followed by its path and then its command-line arguments.  As a result,
the previous implementation of this program failed to correctly detect
existing instances of any such directly-run shebang'd scripts.
