The trace shell option of pman is no longer working. Pman hangs
forever when you try to trace the shell process.

The problem is in pman_shell:find_shell function. It assumes the shell
process is the one that has the {initial_call,{shell,evaluator,3}}
tuple within its process info, but some change has broken this: a process
created with spawn_link will have {erlang, apply, 2} as its initial_call
value.

I've attached a patch that solves the pman problem adding a dictionary
entry so that the shell process can be recognized again, but seems a
"dirty" solution. IMO it would be worth restoring the former behaviour
of the spawn functions, but it is beyond my knowledge so far :(

Any ideas?

Best regards.
